Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72504, here are decompositions:

  • 7 + 72497 = 72504
  • 11 + 72493 = 72504
  • 23 + 72481 = 72504
  • 37 + 72467 = 72504
  • 43 + 72461 = 72504
  • 73 + 72431 = 72504
  • 83 + 72421 = 72504
  • 137 + 72367 = 72504

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.
