Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25564, here are decompositions:

  • 3 + 25561 = 25564
  • 23 + 25541 = 25564
  • 41 + 25523 = 25564
  • 101 + 25463 = 25564
  • 107 + 25457 = 25564
  • 173 + 25391 = 25564
  • 191 + 25373 = 25564
  • 197 + 25367 = 25564

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.
