Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147483756, here are decompositions:

  • 13 + 2147483743 = 2147483756
  • 43 + 2147483713 = 2147483756
  • 97 + 2147483659 = 2147483756
  • 109 + 2147483647 = 2147483756
  • 127 + 2147483629 = 2147483756
  • 193 + 2147483563 = 2147483756
  • 433 + 2147483323 = 2147483756
  • 487 + 2147483269 = 2147483756

Showing the first eight; more decompositions exist.
