Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147480660, here are decompositions:

  • 19 + 2147480641 = 2147480660
  • 37 + 2147480623 = 2147480660
  • 109 + 2147480551 = 2147480660
  • 223 + 2147480437 = 2147480660
  • 349 + 2147480311 = 2147480660
  • 433 + 2147480227 = 2147480660
  • 463 + 2147480197 = 2147480660
  • 499 + 2147480161 = 2147480660

Showing the first eight; more decompositions exist.
