Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525826, here are decompositions:

  • 43 + 31525783 = 31525826
  • 103 + 31525723 = 31525826
  • 109 + 31525717 = 31525826
  • 127 + 31525699 = 31525826
  • 139 + 31525687 = 31525826
  • 223 + 31525603 = 31525826
  • 337 + 31525489 = 31525826
  • 349 + 31525477 = 31525826

Showing the first eight; more decompositions exist.

Federal Reserve
Federal Reserve district 3 (Philadelphia)

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