Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31486110, here are decompositions:

23 + 31486087 = 31486110
101 + 31486009 = 31486110
137 + 31485973 = 31486110
151 + 31485959 = 31486110
157 + 31485953 = 31486110
179 + 31485931 = 31486110
193 + 31485917 = 31486110
239 + 31485871 = 31486110

Showing the first eight; more decompositions exist.
