Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33620688, here are decompositions:

  • 7 + 33620681 = 33620688
  • 29 + 33620659 = 33620688
  • 61 + 33620627 = 33620688
  • 67 + 33620621 = 33620688
  • 71 + 33620617 = 33620688
  • 97 + 33620591 = 33620688
  • 109 + 33620579 = 33620688
  • 151 + 33620537 = 33620688

Showing the first eight; more decompositions exist.
