Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147456630, here are decompositions:

  • 19 + 2147456611 = 2147456630
  • 31 + 2147456599 = 2147456630
  • 97 + 2147456533 = 2147456630
  • 229 + 2147456401 = 2147456630
  • 313 + 2147456317 = 2147456630
  • 331 + 2147456299 = 2147456630
  • 523 + 2147456107 = 2147456630
  • 541 + 2147456089 = 2147456630

Showing the first eight; more decompositions exist.
