Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613148, here are decompositions:

5 + 31613143 = 31613148
11 + 31613137 = 31613148
29 + 31613119 = 31613148
31 + 31613117 = 31613148
41 + 31613107 = 31613148
157 + 31612991 = 31613148
167 + 31612981 = 31613148
179 + 31612969 = 31613148

Showing the first eight; more decompositions exist.
