Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147487376, here are decompositions:

  • 3 + 2147487373 = 2147487376
  • 17 + 2147487359 = 2147487376
  • 107 + 2147487269 = 2147487376
  • 149 + 2147487227 = 2147487376
  • 173 + 2147487203 = 2147487376
  • 263 + 2147487113 = 2147487376
  • 317 + 2147487059 = 2147487376
  • 347 + 2147487029 = 2147487376

Showing the first eight; more decompositions exist.
