Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8635648, here are decompositions:

  • 11 + 8635637 = 8635648
  • 17 + 8635631 = 8635648
  • 41 + 8635607 = 8635648
  • 89 + 8635559 = 8635648
  • 179 + 8635469 = 8635648
  • 239 + 8635409 = 8635648
  • 389 + 8635259 = 8635648
  • 449 + 8635199 = 8635648

Showing the first eight; more decompositions exist.
