Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147483864, here are decompositions:

  • 7 + 2147483857 = 2147483864
  • 151 + 2147483713 = 2147483864
  • 277 + 2147483587 = 2147483864
  • 367 + 2147483497 = 2147483864
  • 541 + 2147483323 = 2147483864
  • 727 + 2147483137 = 2147483864
  • 787 + 2147483077 = 2147483864
  • 811 + 2147483053 = 2147483864

Showing the first eight; more decompositions exist.
