Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66112, here are decompositions:

  • 3 + 66109 = 66112
  • 5 + 66107 = 66112
  • 23 + 66089 = 66112
  • 29 + 66083 = 66112
  • 41 + 66071 = 66112
  • 71 + 66041 = 66112
  • 83 + 66029 = 66112
  • 131 + 65981 = 66112

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.
