Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147500768, here are decompositions:

  • 5 + 2147500763 = 2147500768
  • 71 + 2147500697 = 2147500768
  • 107 + 2147500661 = 2147500768
  • 269 + 2147500499 = 2147500768
  • 467 + 2147500301 = 2147500768
  • 509 + 2147500259 = 2147500768
  • 521 + 2147500247 = 2147500768
  • 641 + 2147500127 = 2147500768

Showing the first eight; more decompositions exist.
