Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 9878, here are decompositions:

  • 7 + 9871 = 9878
  • 19 + 9859 = 9878
  • 61 + 9817 = 9878
  • 67 + 9811 = 9878
  • 97 + 9781 = 9878
  • 109 + 9769 = 9878
  • 139 + 9739 = 9878
  • 157 + 9721 = 9878

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.
