Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33621368, here are decompositions:

  • 7 + 33621361 = 33621368
  • 199 + 33621169 = 33621368
  • 331 + 33621037 = 33621368
  • 337 + 33621031 = 33621368
  • 409 + 33620959 = 33621368
  • 439 + 33620929 = 33621368
  • 457 + 33620911 = 33621368
  • 601 + 33620767 = 33621368

Showing the first eight; more decompositions exist.
