Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33621988, here are decompositions:

  • 107 + 33621881 = 33621988
  • 131 + 33621857 = 33621988
  • 149 + 33621839 = 33621988
  • 227 + 33621761 = 33621988
  • 359 + 33621629 = 33621988
  • 599 + 33621389 = 33621988
  • 677 + 33621311 = 33621988
  • 839 + 33621149 = 33621988

Showing the first eight; more decompositions exist.
