Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147468816, here are decompositions:

  • 7 + 2147468809 = 2147468816
  • 13 + 2147468803 = 2147468816
  • 37 + 2147468779 = 2147468816
  • 43 + 2147468773 = 2147468816
  • 313 + 2147468503 = 2147468816
  • 373 + 2147468443 = 2147468816
  • 499 + 2147468317 = 2147468816
  • 547 + 2147468269 = 2147468816

Showing the first eight; more decompositions exist.
