Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147466918, here are decompositions:

  • 71 + 2147466847 = 2147466918
  • 131 + 2147466787 = 2147466918
  • 197 + 2147466721 = 2147466918
  • 239 + 2147466679 = 2147466918
  • 277 + 2147466641 = 2147466918
  • 379 + 2147466539 = 2147466918
  • 397 + 2147466521 = 2147466918
  • 431 + 2147466487 = 2147466918

Showing the first eight; more decompositions exist.
