Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77172, here are decompositions:

  • 5 + 77167 = 77172
  • 19 + 77153 = 77172
  • 31 + 77141 = 77172
  • 71 + 77101 = 77172
  • 79 + 77093 = 77172
  • 103 + 77069 = 77172
  • 131 + 77041 = 77172
  • 149 + 77023 = 77172

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.
