Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8690320, here are decompositions:

  • 3 + 8690317 = 8690320
  • 17 + 8690303 = 8690320
  • 29 + 8690291 = 8690320
  • 53 + 8690267 = 8690320
  • 227 + 8690093 = 8690320
  • 251 + 8690069 = 8690320
  • 257 + 8690063 = 8690320
  • 467 + 8689853 = 8690320

Showing the first eight; more decompositions exist.
