Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31608470, here are decompositions:

43 + 31608427 = 31608470
151 + 31608319 = 31608470
199 + 31608271 = 31608470
307 + 31608163 = 31608470
337 + 31608133 = 31608470
379 + 31608091 = 31608470
409 + 31608061 = 31608470
433 + 31608037 = 31608470

Showing the first eight; more decompositions exist.
