Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31608524, here are decompositions:

43 + 31608481 = 31608524
97 + 31608427 = 31608524
223 + 31608301 = 31608524
307 + 31608217 = 31608524
433 + 31608091 = 31608524
457 + 31608067 = 31608524
463 + 31608061 = 31608524
487 + 31608037 = 31608524

Showing the first eight; more decompositions exist.
