Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147490838, here are decompositions:

  • 5 + 2147490833 = 2147490838
  • 41 + 2147490797 = 2147490838
  • 107 + 2147490731 = 2147490838
  • 149 + 2147490689 = 2147490838
  • 179 + 2147490659 = 2147490838
  • 257 + 2147490581 = 2147490838
  • 281 + 2147490557 = 2147490838
  • 599 + 2147490239 = 2147490838

Showing the first eight; more decompositions exist.
