Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147466856, here are decompositions:

  • 23 + 2147466833 = 2147466856
  • 173 + 2147466683 = 2147466856
  • 317 + 2147466539 = 2147466856
  • 593 + 2147466263 = 2147466856
  • 599 + 2147466257 = 2147466856
  • 617 + 2147466239 = 2147466856
  • 677 + 2147466179 = 2147466856
  • 839 + 2147466017 = 2147466856

Showing the first eight; more decompositions exist.
