Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72038, here are decompositions:

  • 7 + 72031 = 72038
  • 19 + 72019 = 72038
  • 67 + 71971 = 72038
  • 97 + 71941 = 72038
  • 139 + 71899 = 72038
  • 151 + 71887 = 72038
  • 157 + 71881 = 72038
  • 229 + 71809 = 72038

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.
