Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42000, here are decompositions:

  • 17 + 41983 = 42000
  • 19 + 41981 = 42000
  • 31 + 41969 = 42000
  • 41 + 41959 = 42000
  • 43 + 41957 = 42000
  • 47 + 41953 = 42000
  • 53 + 41947 = 42000
  • 59 + 41941 = 42000

Showing the first eight; more decompositions exist.

Banks operate many routing numbers per state and division; an unmatched checksum-valid number can still be a real RTN at a smaller institution.
