Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294986920, here are decompositions:

13 + 4294986907 = 4294986920
31 + 4294986889 = 4294986920
127 + 4294986793 = 4294986920
139 + 4294986781 = 4294986920
157 + 4294986763 = 4294986920
163 + 4294986757 = 4294986920
271 + 4294986649 = 4294986920
277 + 4294986643 = 4294986920

Showing the first eight; more decompositions exist.
