Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8647636, here are decompositions:

  • 47 + 8647589 = 8647636
  • 167 + 8647469 = 8647636
  • 227 + 8647409 = 8647636
  • 269 + 8647367 = 8647636
  • 359 + 8647277 = 8647636
  • 383 + 8647253 = 8647636
  • 443 + 8647193 = 8647636
  • 479 + 8647157 = 8647636

Showing the first eight; more decompositions exist.
