Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612632, here are decompositions:

  • 5 + 31612627 = 31612632
  • 11 + 31612621 = 31612632
  • 13 + 31612619 = 31612632
  • 43 + 31612589 = 31612632
  • 59 + 31612573 = 31612632
  • 101 + 31612531 = 31612632
  • 151 + 31612481 = 31612632
  • 179 + 31612453 = 31612632

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.
