Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33599720, here are decompositions:

  • 3 + 33599717 = 33599720
  • 43 + 33599677 = 33599720
  • 61 + 33599659 = 33599720
  • 73 + 33599647 = 33599720
  • 163 + 33599557 = 33599720
  • 199 + 33599521 = 33599720
  • 379 + 33599341 = 33599720
  • 397 + 33599323 = 33599720

Showing the first eight; more decompositions exist.
