Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8745688, here are decompositions:

  • 5 + 8745683 = 8745688
  • 11 + 8745677 = 8745688
  • 131 + 8745557 = 8745688
  • 137 + 8745551 = 8745688
  • 239 + 8745449 = 8745688
  • 251 + 8745437 = 8745688
  • 269 + 8745419 = 8745688
  • 359 + 8745329 = 8745688

Showing the first eight; more decompositions exist.
