Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147562646, here are decompositions:

  • 3 + 2147562643 = 2147562646
  • 29 + 2147562617 = 2147562646
  • 107 + 2147562539 = 2147562646
  • 149 + 2147562497 = 2147562646
  • 179 + 2147562467 = 2147562646
  • 269 + 2147562377 = 2147562646
  • 419 + 2147562227 = 2147562646
  • 443 + 2147562203 = 2147562646

Showing the first eight; more decompositions exist.
