Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 23278, here are decompositions:

  • 89 + 23189 = 23278
  • 179 + 23099 = 23278
  • 191 + 23087 = 23278
  • 197 + 23081 = 23278
  • 239 + 23039 = 23278
  • 251 + 23027 = 23278
  • 257 + 23021 = 23278
  • 317 + 22961 = 23278

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.
