Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31573326, here are decompositions:

47 + 31573279 = 31573326
67 + 31573259 = 31573326
73 + 31573253 = 31573326
137 + 31573189 = 31573326
163 + 31573163 = 31573326
173 + 31573153 = 31573326
193 + 31573133 = 31573326
199 + 31573127 = 31573326

Showing the first eight; more decompositions exist.
