Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147477836, here are decompositions:

  • 3 + 2147477833 = 2147477836
  • 29 + 2147477807 = 2147477836
  • 137 + 2147477699 = 2147477836
  • 149 + 2147477687 = 2147477836
  • 443 + 2147477393 = 2147477836
  • 563 + 2147477273 = 2147477836
  • 587 + 2147477249 = 2147477836
  • 599 + 2147477237 = 2147477836

Showing the first eight; more decompositions exist.
