Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8635278, here are decompositions:

  • 5 + 8635273 = 8635278
  • 17 + 8635261 = 8635278
  • 19 + 8635259 = 8635278
  • 37 + 8635241 = 8635278
  • 59 + 8635219 = 8635278
  • 79 + 8635199 = 8635278
  • 137 + 8635141 = 8635278
  • 191 + 8635087 = 8635278

Showing the first eight; more decompositions exist.
