Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28312, here are decompositions:

  • 3 + 28309 = 28312
  • 5 + 28307 = 28312
  • 23 + 28289 = 28312
  • 29 + 28283 = 28312
  • 83 + 28229 = 28312
  • 101 + 28211 = 28312
  • 131 + 28181 = 28312
  • 149 + 28163 = 28312

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.
