Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147375630, here are decompositions:

  • 3 + 2147375627 = 2147375630
  • 61 + 2147375569 = 2147375630
  • 109 + 2147375521 = 2147375630
  • 193 + 2147375437 = 2147375630
  • 223 + 2147375407 = 2147375630
  • 241 + 2147375389 = 2147375630
  • 373 + 2147375257 = 2147375630
  • 457 + 2147375173 = 2147375630

Showing the first eight; more decompositions exist.
