Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8628540, here are decompositions:

  • 47 + 8628493 = 8628540
  • 59 + 8628481 = 8628540
  • 61 + 8628479 = 8628540
  • 97 + 8628443 = 8628540
  • 157 + 8628383 = 8628540
  • 163 + 8628377 = 8628540
  • 181 + 8628359 = 8628540
  • 191 + 8628349 = 8628540

Showing the first eight; more decompositions exist.
