Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147477468, here are decompositions:

  • 277 + 2147477191 = 2147477468
  • 439 + 2147477029 = 2147477468
  • 541 + 2147476927 = 2147477468
  • 571 + 2147476897 = 2147477468
  • 691 + 2147476777 = 2147477468
  • 727 + 2147476741 = 2147477468
  • 769 + 2147476699 = 2147477468
  • 1051 + 2147476417 = 2147477468

Showing the first eight; more decompositions exist.
