Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8643916, here are decompositions:

  • 23 + 8643893 = 8643916
  • 137 + 8643779 = 8643916
  • 167 + 8643749 = 8643916
  • 269 + 8643647 = 8643916
  • 353 + 8643563 = 8643916
  • 389 + 8643527 = 8643916
  • 557 + 8643359 = 8643916
  • 599 + 8643317 = 8643916

Showing the first eight; more decompositions exist.
