Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147427446, here are decompositions:

  • 19 + 2147427427 = 2147427446
  • 277 + 2147427169 = 2147427446
  • 457 + 2147426989 = 2147427446
  • 823 + 2147426623 = 2147427446
  • 919 + 2147426527 = 2147427446
  • 1069 + 2147426377 = 2147427446
  • 1093 + 2147426353 = 2147427446
  • 1117 + 2147426329 = 2147427446

Showing the first eight; more decompositions exist.
