Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4295028678, here are decompositions:

19 + 4295028659 = 4295028678
67 + 4295028611 = 4295028678
71 + 4295028607 = 4295028678
79 + 4295028599 = 4295028678
107 + 4295028571 = 4295028678
181 + 4295028497 = 4295028678
197 + 4295028481 = 4295028678
229 + 4295028449 = 4295028678

Showing the first eight; more decompositions exist.
