Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31573294, here are decompositions:

17 + 31573277 = 31573294
41 + 31573253 = 31573294
83 + 31573211 = 31573294
131 + 31573163 = 31573294
167 + 31573127 = 31573294
191 + 31573103 = 31573294
257 + 31573037 = 31573294
353 + 31572941 = 31573294

Showing the first eight; more decompositions exist.
