Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147501986, here are decompositions:

  • 5 + 2147501981 = 2147501986
  • 17 + 2147501969 = 2147501986
  • 269 + 2147501717 = 2147501986
  • 317 + 2147501669 = 2147501986
  • 359 + 2147501627 = 2147501986
  • 467 + 2147501519 = 2147501986
  • 683 + 2147501303 = 2147501986
  • 809 + 2147501177 = 2147501986

Showing the first eight; more decompositions exist.
