Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294977918, here are decompositions:

19 + 4294977899 = 4294977918
37 + 4294977881 = 4294977918
59 + 4294977859 = 4294977918
71 + 4294977847 = 4294977918
79 + 4294977839 = 4294977918
131 + 4294977787 = 4294977918
149 + 4294977769 = 4294977918
157 + 4294977761 = 4294977918

Showing the first eight; more decompositions exist.
