Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523358, here are decompositions:

11 + 31523347 = 31523358
29 + 31523329 = 31523358
79 + 31523279 = 31523358
107 + 31523251 = 31523358
127 + 31523231 = 31523358
131 + 31523227 = 31523358
137 + 31523221 = 31523358
149 + 31523209 = 31523358

Showing the first eight; more decompositions exist.
