Random numbers.

When people die, they don't have even numbers in their bank account. An estate will often be for some real random number, not some even number of millions of dollars.

When countries run lottos, people don't win random amounts; they win even dollar amounts. Someone usually will win $5 million in a lotto, but inherit $1,341,398.44. It's just the nature of estates verses lottos.

Or so I thought. Apparently the United Kingdom not only draws a random number to pick a winner, but according to this spam, they also apparently draw a random number for the amount of the award:
