Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31486104, here are decompositions:

17 + 31486087 = 31486104
71 + 31486033 = 31486104
131 + 31485973 = 31486104
151 + 31485953 = 31486104
163 + 31485941 = 31486104
173 + 31485931 = 31486104
211 + 31485893 = 31486104
233 + 31485871 = 31486104

Showing the first eight; more decompositions exist.
