Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147500318, here are decompositions:

  • 17 + 2147500301 = 2147500318
  • 59 + 2147500259 = 2147500318
  • 71 + 2147500247 = 2147500318
  • 179 + 2147500139 = 2147500318
  • 191 + 2147500127 = 2147500318
  • 269 + 2147500049 = 2147500318
  • 311 + 2147500007 = 2147500318
  • 401 + 2147499917 = 2147500318

Showing the first eight; more decompositions exist.
