Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8646650, here are decompositions:

  • 43 + 8646607 = 8646650
  • 79 + 8646571 = 8646650
  • 139 + 8646511 = 8646650
  • 163 + 8646487 = 8646650
  • 193 + 8646457 = 8646650
  • 373 + 8646277 = 8646650
  • 487 + 8646163 = 8646650
  • 547 + 8646103 = 8646650

Showing the first eight; more decompositions exist.
