Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33620816, here are decompositions:

  • 3 + 33620813 = 33620816
  • 7 + 33620809 = 33620816
  • 13 + 33620803 = 33620816
  • 67 + 33620749 = 33620816
  • 109 + 33620707 = 33620816
  • 127 + 33620689 = 33620816
  • 157 + 33620659 = 33620816
  • 193 + 33620623 = 33620816

Showing the first eight; more decompositions exist.
