Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 64800, here are decompositions:

  • 7 + 64793 = 64800
  • 17 + 64783 = 64800
  • 19 + 64781 = 64800
  • 37 + 64763 = 64800
  • 53 + 64747 = 64800
  • 83 + 64717 = 64800
  • 107 + 64693 = 64800
  • 137 + 64663 = 64800

Showing the first eight; more decompositions exist.

Banks operate many routing numbers per state and division; an unmatched checksum-valid number can still be a real RTN at a smaller institution.
