Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 26440, here are decompositions:

  • 3 + 26437 = 26440
  • 17 + 26423 = 26440
  • 23 + 26417 = 26440
  • 41 + 26399 = 26440
  • 47 + 26393 = 26440
  • 53 + 26387 = 26440
  • 83 + 26357 = 26440
  • 101 + 26339 = 26440

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.
