Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147466870, here are decompositions:

  • 23 + 2147466847 = 2147466870
  • 37 + 2147466833 = 2147466870
  • 83 + 2147466787 = 2147466870
  • 149 + 2147466721 = 2147466870
  • 191 + 2147466679 = 2147466870
  • 229 + 2147466641 = 2147466870
  • 281 + 2147466589 = 2147466870
  • 331 + 2147466539 = 2147466870

Showing the first eight; more decompositions exist.
