Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8629628, here are decompositions:

  • 31 + 8629597 = 8629628
  • 67 + 8629561 = 8629628
  • 181 + 8629447 = 8629628
  • 199 + 8629429 = 8629628
  • 331 + 8629297 = 8629628
  • 349 + 8629279 = 8629628
  • 457 + 8629171 = 8629628
  • 487 + 8629141 = 8629628

Showing the first eight; more decompositions exist.
