Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4295028640, here are decompositions:

17 + 4295028623 = 4295028640
29 + 4295028611 = 4295028640
41 + 4295028599 = 4295028640
53 + 4295028587 = 4295028640
137 + 4295028503 = 4295028640
191 + 4295028449 = 4295028640
197 + 4295028443 = 4295028640
233 + 4295028407 = 4295028640

Showing the first eight; more decompositions exist.
