Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 45780, here are decompositions:

  • 13 + 45767 = 45780
  • 17 + 45763 = 45780
  • 23 + 45757 = 45780
  • 29 + 45751 = 45780
  • 43 + 45737 = 45780
  • 73 + 45707 = 45780
  • 83 + 45697 = 45780
  • 89 + 45691 = 45780

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.
