Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613166, here are decompositions:

23 + 31613143 = 31613166
29 + 31613137 = 31613166
47 + 31613119 = 31613166
59 + 31613107 = 31613166
113 + 31613053 = 31613166
139 + 31613027 = 31613166
197 + 31612969 = 31613166
227 + 31612939 = 31613166

Showing the first eight; more decompositions exist.
