Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147487340, here are decompositions:

  • 71 + 2147487269 = 2147487340
  • 113 + 2147487227 = 2147487340
  • 137 + 2147487203 = 2147487340
  • 227 + 2147487113 = 2147487340
  • 263 + 2147487077 = 2147487340
  • 281 + 2147487059 = 2147487340
  • 311 + 2147487029 = 2147487340
  • 359 + 2147486981 = 2147487340

Showing the first eight; more decompositions exist.
