Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27740, here are decompositions:

  • 3 + 27737 = 27740
  • 7 + 27733 = 27740
  • 43 + 27697 = 27740
  • 67 + 27673 = 27740
  • 109 + 27631 = 27740
  • 157 + 27583 = 27740
  • 199 + 27541 = 27740
  • 211 + 27529 = 27740

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.
