Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 17886, here are decompositions:

  • 5 + 17881 = 17886
  • 23 + 17863 = 17886
  • 47 + 17839 = 17886
  • 59 + 17827 = 17886
  • 79 + 17807 = 17886
  • 97 + 17789 = 17886
  • 103 + 17783 = 17886
  • 137 + 17749 = 17886

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.
