Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 45450, here are decompositions:

  • 11 + 45439 = 45450
  • 17 + 45433 = 45450
  • 23 + 45427 = 45450
  • 37 + 45413 = 45450
  • 47 + 45403 = 45450
  • 61 + 45389 = 45450
  • 73 + 45377 = 45450
  • 89 + 45361 = 45450

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.
