Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4242, here are decompositions:

  • 11 + 4231 = 4242
  • 13 + 4229 = 4242
  • 23 + 4219 = 4242
  • 31 + 4211 = 4242
  • 41 + 4201 = 4242
  • 83 + 4159 = 4242
  • 89 + 4153 = 4242
  • 103 + 4139 = 4242

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.
