Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294990620, here are decompositions:

23 + 4294990597 = 4294990620
43 + 4294990577 = 4294990620
59 + 4294990561 = 4294990620
157 + 4294990463 = 4294990620
191 + 4294990429 = 4294990620
197 + 4294990423 = 4294990620
211 + 4294990409 = 4294990620
269 + 4294990351 = 4294990620

Showing the first eight; more decompositions exist.
