Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294990660, here are decompositions:

3 + 4294990657 = 4294990660
17 + 4294990643 = 4294990660
29 + 4294990631 = 4294990660
83 + 4294990577 = 4294990660
131 + 4294990529 = 4294990660
197 + 4294990463 = 4294990660
251 + 4294990409 = 4294990660
419 + 4294990241 = 4294990660

Showing the first eight; more decompositions exist.
