Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31573366, here are decompositions:

3 + 31573363 = 31573366
5 + 31573361 = 31573366
89 + 31573277 = 31573366
107 + 31573259 = 31573366
113 + 31573253 = 31573366
233 + 31573133 = 31573366
239 + 31573127 = 31573366
257 + 31573109 = 31573366

Showing the first eight; more decompositions exist.
