Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31573330, here are decompositions:

53 + 31573277 = 31573330
71 + 31573259 = 31573330
167 + 31573163 = 31573330
179 + 31573151 = 31573330
197 + 31573133 = 31573330
227 + 31573103 = 31573330
293 + 31573037 = 31573330
359 + 31572971 = 31573330

Showing the first eight; more decompositions exist.
