Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613112, here are decompositions:

5 + 31613107 = 31613112
59 + 31613053 = 31613112
131 + 31612981 = 31613112
151 + 31612961 = 31613112
173 + 31612939 = 31613112
199 + 31612913 = 31613112
239 + 31612873 = 31613112
281 + 31612831 = 31613112

Showing the first eight; more decompositions exist.
