Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147466668, here are decompositions:

79 + 2147466589 = 2147466668
181 + 2147466487 = 2147466668
211 + 2147466457 = 2147466668
229 + 2147466439 = 2147466668
241 + 2147466427 = 2147466668
331 + 2147466337 = 2147466668
349 + 2147466319 = 2147466668
367 + 2147466301 = 2147466668

Showing the first eight; more decompositions exist.
