Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147484278, here are decompositions:

  • 7 + 2147484271 = 2147484278
  • 19 + 2147484259 = 2147484278
  • 241 + 2147484037 = 2147484278
  • 271 + 2147484007 = 2147484278
  • 349 + 2147483929 = 2147484278
  • 409 + 2147483869 = 2147484278
  • 421 + 2147483857 = 2147484278
  • 619 + 2147483659 = 2147484278

Showing the first eight; more decompositions exist.
