Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147384732, here are decompositions:

  • 43 + 2147384689 = 2147384732
  • 79 + 2147384653 = 2147384732
  • 139 + 2147384593 = 2147384732
  • 223 + 2147384509 = 2147384732
  • 541 + 2147384191 = 2147384732
  • 643 + 2147384089 = 2147384732
  • 709 + 2147384023 = 2147384732
  • 733 + 2147383999 = 2147384732

Showing the first eight; more decompositions exist.
