Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31485964, here are decompositions:

5 + 31485959 = 31485964
11 + 31485953 = 31485964
23 + 31485941 = 31485964
47 + 31485917 = 31485964
71 + 31485893 = 31485964
131 + 31485833 = 31485964
173 + 31485791 = 31485964
197 + 31485767 = 31485964

Showing the first eight; more decompositions exist.
