Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147399762, here are decompositions:

  • 3 + 2147399759 = 2147399762
  • 31 + 2147399731 = 2147399762
  • 43 + 2147399719 = 2147399762
  • 61 + 2147399701 = 2147399762
  • 73 + 2147399689 = 2147399762
  • 181 + 2147399581 = 2147399762
  • 229 + 2147399533 = 2147399762
  • 241 + 2147399521 = 2147399762

Showing the first eight; more decompositions exist.
