Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31486050, here are decompositions:

17 + 31486033 = 31486050
41 + 31486009 = 31486050
97 + 31485953 = 31486050
109 + 31485941 = 31486050
157 + 31485893 = 31486050
179 + 31485871 = 31486050
227 + 31485823 = 31486050
251 + 31485799 = 31486050

Showing the first eight; more decompositions exist.
