Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613150, here are decompositions:

7 + 31613143 = 31613150
13 + 31613137 = 31613150
31 + 31613119 = 31613150
43 + 31613107 = 31613150
97 + 31613053 = 31613150
181 + 31612969 = 31613150
199 + 31612951 = 31613150
211 + 31612939 = 31613150

Showing the first eight; more decompositions exist.
