Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31608176, here are decompositions:

7 + 31608169 = 31608176
13 + 31608163 = 31608176
43 + 31608133 = 31608176
109 + 31608067 = 31608176
139 + 31608037 = 31608176
163 + 31608013 = 31608176
307 + 31607869 = 31608176
337 + 31607839 = 31608176

Showing the first eight; more decompositions exist.
