Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4295066640, here are decompositions:

13 + 4295066627 = 4295066640
47 + 4295066593 = 4295066640
61 + 4295066579 = 4295066640
103 + 4295066537 = 4295066640
107 + 4295066533 = 4295066640
131 + 4295066509 = 4295066640
149 + 4295066491 = 4295066640
181 + 4295066459 = 4295066640

Showing the first eight; more decompositions exist.
