Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3926, here are decompositions:

  • 3 + 3923 = 3926
  • 7 + 3919 = 3926
  • 19 + 3907 = 3926
  • 37 + 3889 = 3926
  • 73 + 3853 = 3926
  • 79 + 3847 = 3926
  • 103 + 3823 = 3926
  • 157 + 3769 = 3926

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.
