Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147476980, here are decompositions:

  • 17 + 2147476963 = 2147476980
  • 29 + 2147476951 = 2147476980
  • 37 + 2147476943 = 2147476980
  • 43 + 2147476937 = 2147476980
  • 53 + 2147476927 = 2147476980
  • 83 + 2147476897 = 2147476980
  • 109 + 2147476871 = 2147476980
  • 139 + 2147476841 = 2147476980

Showing the first eight; more decompositions exist.
