Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294986978, here are decompositions:

11 + 4294986967 = 4294986978
19 + 4294986959 = 4294986978
67 + 4294986911 = 4294986978
71 + 4294986907 = 4294986978
89 + 4294986889 = 4294986978
127 + 4294986851 = 4294986978
197 + 4294986781 = 4294986978
211 + 4294986767 = 4294986978

Showing the first eight; more decompositions exist.
