Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147429222, here are decompositions:

  • 151 + 2147429071 = 2147429222
  • 199 + 2147429023 = 2147429222
  • 223 + 2147428999 = 2147429222
  • 241 + 2147428981 = 2147429222
  • 331 + 2147428891 = 2147429222
  • 439 + 2147428783 = 2147429222
  • 661 + 2147428561 = 2147429222
  • 733 + 2147428489 = 2147429222

Showing the first eight; more decompositions exist.
