Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31573396, here are decompositions:

3 + 31573393 = 31573396
5 + 31573391 = 31573396
137 + 31573259 = 31573396
233 + 31573163 = 31573396
263 + 31573133 = 31573396
269 + 31573127 = 31573396
293 + 31573103 = 31573396
359 + 31573037 = 31573396

Showing the first eight; more decompositions exist.
