Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147500312, here are decompositions:

  • 11 + 2147500301 = 2147500312
  • 53 + 2147500259 = 2147500312
  • 71 + 2147500241 = 2147500312
  • 173 + 2147500139 = 2147500312
  • 263 + 2147500049 = 2147500312
  • 359 + 2147499953 = 2147500312
  • 389 + 2147499923 = 2147500312
  • 449 + 2147499863 = 2147500312

Showing the first eight; more decompositions exist.
