Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147488670, here are decompositions:

  • 97 + 2147488573 = 2147488670
  • 127 + 2147488543 = 2147488670
  • 241 + 2147488429 = 2147488670
  • 337 + 2147488333 = 2147488670
  • 421 + 2147488249 = 2147488670
  • 499 + 2147488171 = 2147488670
  • 643 + 2147488027 = 2147488670
  • 661 + 2147488009 = 2147488670

Showing the first eight; more decompositions exist.
