Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294991940, here are decompositions:

13 + 4294991927 = 4294991940
17 + 4294991923 = 4294991940
47 + 4294991893 = 4294991940
53 + 4294991887 = 4294991940
67 + 4294991873 = 4294991940
79 + 4294991861 = 4294991940
101 + 4294991839 = 4294991940
103 + 4294991837 = 4294991940

Showing the first eight; more decompositions exist.
