Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 84220, here are decompositions:

  • 29 + 84191 = 84220
  • 41 + 84179 = 84220
  • 83 + 84137 = 84220
  • 89 + 84131 = 84220
  • 131 + 84089 = 84220
  • 167 + 84053 = 84220
  • 173 + 84047 = 84220
  • 233 + 83987 = 84220

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.
