Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20776, here are decompositions:

  • 3 + 20773 = 20776
  • 5 + 20771 = 20776
  • 17 + 20759 = 20776
  • 23 + 20753 = 20776
  • 29 + 20747 = 20776
  • 59 + 20717 = 20776
  • 83 + 20693 = 20776
  • 113 + 20663 = 20776

Showing the first eight; more decompositions exist.

Possible US bank routing number

This passes the ABA routing number checksum and matches the Federal Reserve numbering scheme.
