Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31486152, here are decompositions:

23 + 31486129 = 31486152
29 + 31486123 = 31486152
31 + 31486121 = 31486152
43 + 31486109 = 31486152
179 + 31485973 = 31486152
193 + 31485959 = 31486152
199 + 31485953 = 31486152
211 + 31485941 = 31486152

Showing the first eight; more decompositions exist.
