Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147481886, here are decompositions:

  • 3 + 2147481883 = 2147481886
  • 23 + 2147481863 = 2147481886
  • 59 + 2147481827 = 2147481886
  • 89 + 2147481797 = 2147481886
  • 257 + 2147481629 = 2147481886
  • 569 + 2147481317 = 2147481886
  • 617 + 2147481269 = 2147481886
  • 677 + 2147481209 = 2147481886

Showing the first eight; more decompositions exist.
