Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25904, here are decompositions:

  • 31 + 25873 = 25904
  • 37 + 25867 = 25904
  • 103 + 25801 = 25904
  • 157 + 25747 = 25904
  • 163 + 25741 = 25904
  • 211 + 25693 = 25904
  • 271 + 25633 = 25904
  • 283 + 25621 = 25904

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.
