Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19622, here are decompositions:

  • 13 + 19609 = 19622
  • 19 + 19603 = 19622
  • 79 + 19543 = 19622
  • 139 + 19483 = 19622
  • 151 + 19471 = 19622
  • 181 + 19441 = 19622
  • 193 + 19429 = 19622
  • 199 + 19423 = 19622

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.
