Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147466890, here are decompositions:

  • 43 + 2147466847 = 2147466890
  • 97 + 2147466793 = 2147466890
  • 103 + 2147466787 = 2147466890
  • 211 + 2147466679 = 2147466890
  • 433 + 2147466457 = 2147466890
  • 463 + 2147466427 = 2147466890
  • 571 + 2147466319 = 2147466890
  • 577 + 2147466313 = 2147466890

Showing the first eight; more decompositions exist.
