Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294957878, here are decompositions:

17 + 4294957861 = 4294957878
19 + 4294957859 = 4294957878
37 + 4294957841 = 4294957878
97 + 4294957781 = 4294957878
149 + 4294957729 = 4294957878
179 + 4294957699 = 4294957878
181 + 4294957697 = 4294957878
199 + 4294957679 = 4294957878

Showing the first eight; more decompositions exist.
