Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147489072, here are decompositions:

  • 13 + 2147489059 = 2147489072
  • 331 + 2147488741 = 2147489072
  • 499 + 2147488573 = 2147489072
  • 643 + 2147488429 = 2147489072
  • 661 + 2147488411 = 2147489072
  • 691 + 2147488381 = 2147489072
  • 739 + 2147488333 = 2147489072
  • 823 + 2147488249 = 2147489072

Showing the first eight; more decompositions exist.
