Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31608326, here are decompositions:

7 + 31608319 = 31608326
109 + 31608217 = 31608326
157 + 31608169 = 31608326
163 + 31608163 = 31608326
193 + 31608133 = 31608326
313 + 31608013 = 31608326
457 + 31607869 = 31608326
487 + 31607839 = 31608326

Showing the first eight; more decompositions exist.
