Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4295002878, here are decompositions:

11 + 4295002867 = 4295002878
17 + 4295002861 = 4295002878
71 + 4295002807 = 4295002878
79 + 4295002799 = 4295002878
107 + 4295002771 = 4295002878
109 + 4295002769 = 4295002878
157 + 4295002721 = 4295002878
181 + 4295002697 = 4295002878

Showing the first eight; more decompositions exist.
