Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147429312, here are decompositions:

  • 3 + 2147429309 = 2147429312
  • 31 + 2147429281 = 2147429312
  • 79 + 2147429233 = 2147429312
  • 139 + 2147429173 = 2147429312
  • 181 + 2147429131 = 2147429312
  • 241 + 2147429071 = 2147429312
  • 313 + 2147428999 = 2147429312
  • 331 + 2147428981 = 2147429312

Showing the first eight; more decompositions exist.
