Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31608236, here are decompositions:

19 + 31608217 = 31608236
67 + 31608169 = 31608236
73 + 31608163 = 31608236
103 + 31608133 = 31608236
199 + 31608037 = 31608236
223 + 31608013 = 31608236
367 + 31607869 = 31608236
379 + 31607857 = 31608236

Showing the first eight; more decompositions exist.
