Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147490808, here are decompositions:

  • 11 + 2147490797 = 2147490808
  • 149 + 2147490659 = 2147490808
  • 227 + 2147490581 = 2147490808
  • 251 + 2147490557 = 2147490808
  • 269 + 2147490539 = 2147490808
  • 569 + 2147490239 = 2147490808
  • 647 + 2147490161 = 2147490808
  • 719 + 2147490089 = 2147490808

Showing the first eight; more decompositions exist.
