Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31608230, here are decompositions:

13 + 31608217 = 31608230
61 + 31608169 = 31608230
67 + 31608163 = 31608230
97 + 31608133 = 31608230
139 + 31608091 = 31608230
163 + 31608067 = 31608230
193 + 31608037 = 31608230
373 + 31607857 = 31608230

Showing the first eight; more decompositions exist.
