Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294991988, here are decompositions:

5 + 4294991983 = 4294991988
11 + 4294991977 = 4294991988
61 + 4294991927 = 4294991988
97 + 4294991891 = 4294991988
101 + 4294991887 = 4294991988
127 + 4294991861 = 4294991988
139 + 4294991849 = 4294991988
149 + 4294991839 = 4294991988

Showing the first eight; more decompositions exist.
