Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147500986, here are decompositions:

  • 5 + 2147500981 = 2147500986
  • 79 + 2147500907 = 2147500986
  • 97 + 2147500889 = 2147500986
  • 107 + 2147500879 = 2147500986
  • 173 + 2147500813 = 2147500986
  • 223 + 2147500763 = 2147500986
  • 263 + 2147500723 = 2147500986
  • 359 + 2147500627 = 2147500986

Showing the first eight; more decompositions exist.
