Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147499294, here are decompositions:

  • 11 + 2147499283 = 2147499294
  • 13 + 2147499281 = 2147499294
  • 41 + 2147499253 = 2147499294
  • 53 + 2147499241 = 2147499294
  • 223 + 2147499071 = 2147499294
  • 257 + 2147499037 = 2147499294
  • 277 + 2147499017 = 2147499294
  • 331 + 2147498963 = 2147499294

Showing the first eight; more decompositions exist.
