Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31486044, here are decompositions:

11 + 31486033 = 31486044
71 + 31485973 = 31486044
103 + 31485941 = 31486044
113 + 31485931 = 31486044
127 + 31485917 = 31486044
151 + 31485893 = 31486044
173 + 31485871 = 31486044
211 + 31485833 = 31486044

Showing the first eight; more decompositions exist.
