Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8706872, here are decompositions:

  • 3 + 8706869 = 8706872
  • 19 + 8706853 = 8706872
  • 43 + 8706829 = 8706872
  • 79 + 8706793 = 8706872
  • 409 + 8706463 = 8706872
  • 523 + 8706349 = 8706872
  • 631 + 8706241 = 8706872
  • 709 + 8706163 = 8706872

Showing the first eight; more decompositions exist.
