Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147560864, here are decompositions:

  • 17 + 2147560847 = 2147560864
  • 47 + 2147560817 = 2147560864
  • 101 + 2147560763 = 2147560864
  • 131 + 2147560733 = 2147560864
  • 227 + 2147560637 = 2147560864
  • 311 + 2147560553 = 2147560864
  • 347 + 2147560517 = 2147560864
  • 353 + 2147560511 = 2147560864

Showing the first eight; more decompositions exist.
