Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31573304, here are decompositions:

43 + 31573261 = 31573304
151 + 31573153 = 31573304
181 + 31573123 = 31573304
193 + 31573111 = 31573304
211 + 31573093 = 31573304
277 + 31573027 = 31573304
283 + 31573021 = 31573304
463 + 31572841 = 31573304

Showing the first eight; more decompositions exist.
