Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8656844, here are decompositions:

  • 13 + 8656831 = 8656844
  • 37 + 8656807 = 8656844
  • 43 + 8656801 = 8656844
  • 241 + 8656603 = 8656844
  • 271 + 8656573 = 8656844
  • 283 + 8656561 = 8656844
  • 307 + 8656537 = 8656844
  • 367 + 8656477 = 8656844

Showing the first eight; more decompositions exist.
