Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147483986, here are decompositions:

  • 173 + 2147483813 = 2147483986
  • 293 + 2147483693 = 2147483986
  • 443 + 2147483543 = 2147483986
  • 509 + 2147483477 = 2147483986
  • 563 + 2147483423 = 2147483986
  • 587 + 2147483399 = 2147483986
  • 863 + 2147483123 = 2147483986
  • 953 + 2147483033 = 2147483986

Showing the first eight; more decompositions exist.
