Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 26660, here are decompositions:

  • 13 + 26647 = 26660
  • 19 + 26641 = 26660
  • 103 + 26557 = 26660
  • 163 + 26497 = 26660
  • 181 + 26479 = 26660
  • 211 + 26449 = 26660
  • 223 + 26437 = 26660
  • 229 + 26431 = 26660

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.
