Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31566324, here are decompositions:

7 + 31566317 = 31566324
37 + 31566287 = 31566324
73 + 31566251 = 31566324
103 + 31566221 = 31566324
157 + 31566167 = 31566324
173 + 31566151 = 31566324
193 + 31566131 = 31566324
241 + 31566083 = 31566324

Showing the first eight; more decompositions exist.
