Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8656442, here are decompositions:

  • 19 + 8656423 = 8656442
  • 31 + 8656411 = 8656442
  • 43 + 8656399 = 8656442
  • 73 + 8656369 = 8656442
  • 79 + 8656363 = 8656442
  • 103 + 8656339 = 8656442
  • 163 + 8656279 = 8656442
  • 211 + 8656231 = 8656442

Showing the first eight; more decompositions exist.
