Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294977978, here are decompositions:

17 + 4294977961 = 4294977978
79 + 4294977899 = 4294977978
97 + 4294977881 = 4294977978
131 + 4294977847 = 4294977978
139 + 4294977839 = 4294977978
191 + 4294977787 = 4294977978
227 + 4294977751 = 4294977978
307 + 4294977671 = 4294977978

Showing the first eight; more decompositions exist.
