Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294986990, here are decompositions:

23 + 4294986967 = 4294986990
31 + 4294986959 = 4294986990
37 + 4294986953 = 4294986990
79 + 4294986911 = 4294986990
83 + 4294986907 = 4294986990
97 + 4294986893 = 4294986990
101 + 4294986889 = 4294986990
127 + 4294986863 = 4294986990

Showing the first eight; more decompositions exist.
