Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 82400, here are decompositions:

  • 7 + 82393 = 82400
  • 13 + 82387 = 82400
  • 61 + 82339 = 82400
  • 139 + 82261 = 82400
  • 163 + 82237 = 82400
  • 181 + 82219 = 82400
  • 193 + 82207 = 82400
  • 211 + 82189 = 82400

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.
