Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4295009778, here are decompositions:

11 + 4295009767 = 4295009778
19 + 4295009759 = 4295009778
41 + 4295009737 = 4295009778
67 + 4295009711 = 4295009778
89 + 4295009689 = 4295009778
97 + 4295009681 = 4295009778
107 + 4295009671 = 4295009778
131 + 4295009647 = 4295009778

Showing the first eight; more decompositions exist.
