Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147466878, here are decompositions:

  • 31 + 2147466847 = 2147466878
  • 157 + 2147466721 = 2147466878
  • 199 + 2147466679 = 2147466878
  • 331 + 2147466547 = 2147466878
  • 421 + 2147466457 = 2147466878
  • 439 + 2147466439 = 2147466878
  • 541 + 2147466337 = 2147466878
  • 577 + 2147466301 = 2147466878

Showing the first eight; more decompositions exist.
