Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66536, here are decompositions:

  • 3 + 66533 = 66536
  • 7 + 66529 = 66536
  • 13 + 66523 = 66536
  • 37 + 66499 = 66536
  • 73 + 66463 = 66536
  • 79 + 66457 = 66536
  • 163 + 66373 = 66536
  • 193 + 66343 = 66536

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.
