Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613184, here are decompositions:

13 + 31613171 = 31613184
41 + 31613143 = 31613184
47 + 31613137 = 31613184
67 + 31613117 = 31613184
131 + 31613053 = 31613184
157 + 31613027 = 31613184
193 + 31612991 = 31613184
223 + 31612961 = 31613184

Showing the first eight; more decompositions exist.
