Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31608362, here are decompositions:

13 + 31608349 = 31608362
43 + 31608319 = 31608362
61 + 31608301 = 31608362
193 + 31608169 = 31608362
199 + 31608163 = 31608362
229 + 31608133 = 31608362
271 + 31608091 = 31608362
349 + 31608013 = 31608362

Showing the first eight; more decompositions exist.
