Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3656, here are decompositions:

  • 13 + 3643 = 3656
  • 19 + 3637 = 3656
  • 43 + 3613 = 3656
  • 73 + 3583 = 3656
  • 97 + 3559 = 3656
  • 109 + 3547 = 3656
  • 127 + 3529 = 3656
  • 139 + 3517 = 3656

Showing the first eight; more decompositions exist.
