Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31450344, here are decompositions:

  • 31 + 31450313 = 31450344
  • 53 + 31450291 = 31450344
  • 73 + 31450271 = 31450344
  • 97 + 31450247 = 31450344
  • 127 + 31450217 = 31450344
  • 137 + 31450207 = 31450344
  • 181 + 31450163 = 31450344
  • 227 + 31450117 = 31450344

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.
