Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617202, here are decompositions:

3 + 31617199 = 31617202
53 + 31617149 = 31617202
101 + 31617101 = 31617202
173 + 31617029 = 31617202
179 + 31617023 = 31617202
191 + 31617011 = 31617202
251 + 31616951 = 31617202
269 + 31616933 = 31617202

Showing the first eight; more decompositions exist.
