Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30672, here are decompositions:

  • 11 + 30661 = 30672
  • 23 + 30649 = 30672
  • 29 + 30643 = 30672
  • 41 + 30631 = 30672
  • 79 + 30593 = 30672
  • 113 + 30559 = 30672
  • 163 + 30509 = 30672
  • 179 + 30493 = 30672

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.
