Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147468358, here are decompositions:

  • 17 + 2147468341 = 2147468358
  • 41 + 2147468317 = 2147468358
  • 67 + 2147468291 = 2147468358
  • 89 + 2147468269 = 2147468358
  • 109 + 2147468249 = 2147468358
  • 127 + 2147468231 = 2147468358
  • 227 + 2147468131 = 2147468358
  • 239 + 2147468119 = 2147468358

Showing the first eight; more decompositions exist.
