Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31573306, here are decompositions:

29 + 31573277 = 31573306
47 + 31573259 = 31573306
53 + 31573253 = 31573306
173 + 31573133 = 31573306
179 + 31573127 = 31573306
197 + 31573109 = 31573306
269 + 31573037 = 31573306
593 + 31572713 = 31573306

Showing the first eight; more decompositions exist.
