Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61816, here are decompositions:

  • 3 + 61813 = 61816
  • 59 + 61757 = 61816
  • 113 + 61703 = 61816
  • 149 + 61667 = 61816
  • 173 + 61643 = 61816
  • 179 + 61637 = 61816
  • 233 + 61583 = 61816
  • 257 + 61559 = 61816

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.
