Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8656486, here are decompositions:

  • 5 + 8656481 = 8656486
  • 17 + 8656469 = 8656486
  • 23 + 8656463 = 8656486
  • 53 + 8656433 = 8656486
  • 107 + 8656379 = 8656486
  • 173 + 8656313 = 8656486
  • 233 + 8656253 = 8656486
  • 317 + 8656169 = 8656486

Showing the first eight; more decompositions exist.
