Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8645744, here are decompositions:

  • 97 + 8645647 = 8645744
  • 127 + 8645617 = 8645744
  • 157 + 8645587 = 8645744
  • 313 + 8645431 = 8645744
  • 337 + 8645407 = 8645744
  • 463 + 8645281 = 8645744
  • 487 + 8645257 = 8645744
  • 631 + 8645113 = 8645744

Showing the first eight; more decompositions exist.
