Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4295021778, here are decompositions:

11 + 4295021767 = 4295021778
29 + 4295021749 = 4295021778
41 + 4295021737 = 4295021778
79 + 4295021699 = 4295021778
97 + 4295021681 = 4295021778
107 + 4295021671 = 4295021778
137 + 4295021641 = 4295021778
139 + 4295021639 = 4295021778

Showing the first eight; more decompositions exist.
