Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147488256, here are decompositions:

  • 7 + 2147488249 = 2147488256
  • 103 + 2147488153 = 2147488256
  • 229 + 2147488027 = 2147488256
  • 349 + 2147487907 = 2147488256
  • 439 + 2147487817 = 2147488256
  • 457 + 2147487799 = 2147488256
  • 499 + 2147487757 = 2147488256
  • 607 + 2147487649 = 2147488256

Showing the first eight; more decompositions exist.
