Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 90078, here are decompositions:

  • 5 + 90073 = 90078
  • 7 + 90071 = 90078
  • 11 + 90067 = 90078
  • 19 + 90059 = 90078
  • 47 + 90031 = 90078
  • 59 + 90019 = 90078
  • 61 + 90017 = 90078
  • 67 + 90011 = 90078

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.
