Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15626, here are decompositions:

  • 7 + 15619 = 15626
  • 19 + 15607 = 15626
  • 43 + 15583 = 15626
  • 67 + 15559 = 15626
  • 199 + 15427 = 15626
  • 277 + 15349 = 15626
  • 307 + 15319 = 15626
  • 313 + 15313 = 15626

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.
