Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 9904, here are decompositions:

  • 3 + 9901 = 9904
  • 17 + 9887 = 9904
  • 47 + 9857 = 9904
  • 53 + 9851 = 9904
  • 71 + 9833 = 9904
  • 101 + 9803 = 9904
  • 113 + 9791 = 9904
  • 137 + 9767 = 9904

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.
