Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31710, here are decompositions:

  • 11 + 31699 = 31710
  • 23 + 31687 = 31710
  • 43 + 31667 = 31710
  • 47 + 31663 = 31710
  • 53 + 31657 = 31710
  • 61 + 31649 = 31710
  • 67 + 31643 = 31710
  • 83 + 31627 = 31710

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.
