Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147468666, here are decompositions:

  • 67 + 2147468599 = 2147468666
  • 103 + 2147468563 = 2147468666
  • 163 + 2147468503 = 2147468666
  • 223 + 2147468443 = 2147468666
  • 349 + 2147468317 = 2147468666
  • 397 + 2147468269 = 2147468666
  • 433 + 2147468233 = 2147468666
  • 547 + 2147468119 = 2147468666

Showing the first eight; more decompositions exist.
