Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8656430, here are decompositions:

  • 7 + 8656423 = 8656430
  • 19 + 8656411 = 8656430
  • 31 + 8656399 = 8656430
  • 37 + 8656393 = 8656430
  • 61 + 8656369 = 8656430
  • 67 + 8656363 = 8656430
  • 73 + 8656357 = 8656430
  • 109 + 8656321 = 8656430

Showing the first eight; more decompositions exist.
