Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31573282, here are decompositions:

3 + 31573279 = 31573282
5 + 31573277 = 31573282
23 + 31573259 = 31573282
29 + 31573253 = 31573282
71 + 31573211 = 31573282
131 + 31573151 = 31573282
149 + 31573133 = 31573282
173 + 31573109 = 31573282

Showing the first eight; more decompositions exist.
