Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147466568, here are decompositions:

  • 29 + 2147466539 = 2147466568
  • 47 + 2147466521 = 2147466568
  • 89 + 2147466479 = 2147466568
  • 239 + 2147466329 = 2147466568
  • 311 + 2147466257 = 2147466568
  • 389 + 2147466179 = 2147466568
  • 419 + 2147466149 = 2147466568
  • 449 + 2147466119 = 2147466568

Showing the first eight; more decompositions exist.
