Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31608308, here are decompositions:

7 + 31608301 = 31608308
37 + 31608271 = 31608308
139 + 31608169 = 31608308
241 + 31608067 = 31608308
271 + 31608037 = 31608308
337 + 31607971 = 31608308
439 + 31607869 = 31608308
619 + 31607689 = 31608308

Showing the first eight; more decompositions exist.
