Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31520352, here are decompositions:

13 + 31520339 = 31520352
43 + 31520309 = 31520352
53 + 31520299 = 31520352
109 + 31520243 = 31520352
151 + 31520201 = 31520352
173 + 31520179 = 31520352
179 + 31520173 = 31520352
181 + 31520171 = 31520352

Showing the first eight; more decompositions exist.
