Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78618, here are decompositions:

  • 11 + 78607 = 78618
  • 41 + 78577 = 78618
  • 47 + 78571 = 78618
  • 79 + 78539 = 78618
  • 101 + 78517 = 78618
  • 107 + 78511 = 78618
  • 109 + 78509 = 78618
  • 131 + 78487 = 78618

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.
