Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40390, here are decompositions:

  • 3 + 40387 = 40390
  • 29 + 40361 = 40390
  • 47 + 40343 = 40390
  • 101 + 40289 = 40390
  • 107 + 40283 = 40390
  • 113 + 40277 = 40390
  • 137 + 40253 = 40390
  • 149 + 40241 = 40390

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.
