Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294965978, here are decompositions:

7 + 4294965971 = 4294965978
11 + 4294965967 = 4294965978
29 + 4294965949 = 4294965978
41 + 4294965937 = 4294965978
67 + 4294965911 = 4294965978
131 + 4294965847 = 4294965978
137 + 4294965841 = 4294965978
139 + 4294965839 = 4294965978

Showing the first eight; more decompositions exist.
