Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 81948, here are decompositions:

  • 5 + 81943 = 81948
  • 11 + 81937 = 81948
  • 17 + 81931 = 81948
  • 19 + 81929 = 81948
  • 29 + 81919 = 81948
  • 47 + 81901 = 81948
  • 79 + 81869 = 81948
  • 101 + 81847 = 81948

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.
