Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147484540, here are decompositions:

  • 13 + 2147484527 = 2147484540
  • 23 + 2147484517 = 2147484540
  • 41 + 2147484499 = 2147484540
  • 79 + 2147484461 = 2147484540
  • 101 + 2147484439 = 2147484540
  • 107 + 2147484433 = 2147484540
  • 163 + 2147484377 = 2147484540
  • 191 + 2147484349 = 2147484540

Showing the first eight; more decompositions exist.
