Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66604, here are decompositions:

  • 3 + 66601 = 66604
  • 11 + 66593 = 66604
  • 17 + 66587 = 66604
  • 71 + 66533 = 66604
  • 113 + 66491 = 66604
  • 137 + 66467 = 66604
  • 173 + 66431 = 66604
  • 191 + 66413 = 66604

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.
