Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147483690, here are decompositions:

  • 31 + 2147483659 = 2147483690
  • 43 + 2147483647 = 2147483690
  • 61 + 2147483629 = 2147483690
  • 103 + 2147483587 = 2147483690
  • 127 + 2147483563 = 2147483690
  • 193 + 2147483497 = 2147483690
  • 337 + 2147483353 = 2147483690
  • 367 + 2147483323 = 2147483690

Showing the first eight; more decompositions exist.
