Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31608306, here are decompositions:

5 + 31608301 = 31608306
43 + 31608263 = 31608306
89 + 31608217 = 31608306
137 + 31608169 = 31608306
139 + 31608167 = 31608306
157 + 31608149 = 31608306
173 + 31608133 = 31608306
199 + 31608107 = 31608306

Showing the first eight; more decompositions exist.
