Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147468508, here are decompositions:

  • 5 + 2147468503 = 2147468508
  • 11 + 2147468497 = 2147468508
  • 79 + 2147468429 = 2147468508
  • 167 + 2147468341 = 2147468508
  • 191 + 2147468317 = 2147468508
  • 239 + 2147468269 = 2147468508
  • 277 + 2147468231 = 2147468508
  • 389 + 2147468119 = 2147468508

Showing the first eight; more decompositions exist.
