Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 68042, here are decompositions:

  • 19 + 68023 = 68042
  • 103 + 67939 = 68042
  • 109 + 67933 = 68042
  • 151 + 67891 = 68042
  • 199 + 67843 = 68042
  • 223 + 67819 = 68042
  • 241 + 67801 = 68042
  • 283 + 67759 = 68042

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.
