Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294975920, here are decompositions:

13 + 4294975907 = 4294975920
29 + 4294975891 = 4294975920
31 + 4294975889 = 4294975920
43 + 4294975877 = 4294975920
71 + 4294975849 = 4294975920
73 + 4294975847 = 4294975920
127 + 4294975793 = 4294975920
139 + 4294975781 = 4294975920

Showing the first eight; more decompositions exist.
