Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294979940, here are decompositions:

7 + 4294979933 = 4294979940
11 + 4294979929 = 4294979940
23 + 4294979917 = 4294979940
59 + 4294979881 = 4294979940
79 + 4294979861 = 4294979940
89 + 4294979851 = 4294979940
109 + 4294979831 = 4294979940
131 + 4294979809 = 4294979940

Showing the first eight; more decompositions exist.
