Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 17530, here are decompositions:

  • 11 + 17519 = 17530
  • 41 + 17489 = 17530
  • 47 + 17483 = 17530
  • 53 + 17477 = 17530
  • 59 + 17471 = 17530
  • 113 + 17417 = 17530
  • 137 + 17393 = 17530
  • 179 + 17351 = 17530

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.
