Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147477814, here are decompositions:

  • 5 + 2147477809 = 2147477814
  • 7 + 2147477807 = 2147477814
  • 113 + 2147477701 = 2147477814
  • 127 + 2147477687 = 2147477814
  • 281 + 2147477533 = 2147477814
  • 283 + 2147477531 = 2147477814
  • 311 + 2147477503 = 2147477814
  • 347 + 2147477467 = 2147477814

Showing the first eight; more decompositions exist.
