Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 34720, here are decompositions:

  • 17 + 34703 = 34720
  • 41 + 34679 = 34720
  • 47 + 34673 = 34720
  • 53 + 34667 = 34720
  • 71 + 34649 = 34720
  • 89 + 34631 = 34720
  • 107 + 34613 = 34720
  • 113 + 34607 = 34720

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.
