Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33557656, here are decompositions:

  • 29 + 33557627 = 33557656
  • 53 + 33557603 = 33557656
  • 59 + 33557597 = 33557656
  • 89 + 33557567 = 33557656
  • 113 + 33557543 = 33557656
  • 227 + 33557429 = 33557656
  • 233 + 33557423 = 33557656
  • 239 + 33557417 = 33557656

Showing the first eight; more decompositions exist.
