Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8728756, here are decompositions:

  • 107 + 8728649 = 8728756
  • 149 + 8728607 = 8728756
  • 359 + 8728397 = 8728756
  • 383 + 8728373 = 8728756
  • 467 + 8728289 = 8728756
  • 563 + 8728193 = 8728756
  • 587 + 8728169 = 8728756
  • 677 + 8728079 = 8728756

Showing the first eight; more decompositions exist.
