Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31573362, here are decompositions:

5 + 31573357 = 31573362
83 + 31573279 = 31573362
101 + 31573261 = 31573362
103 + 31573259 = 31573362
109 + 31573253 = 31573362
151 + 31573211 = 31573362
173 + 31573189 = 31573362
199 + 31573163 = 31573362

Showing the first eight; more decompositions exist.
