Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31516326, here are decompositions:

7 + 31516319 = 31516326
29 + 31516297 = 31516326
73 + 31516253 = 31516326
89 + 31516237 = 31516326
137 + 31516189 = 31516326
167 + 31516159 = 31516326
173 + 31516153 = 31516326
197 + 31516129 = 31516326

Showing the first eight; more decompositions exist.
