Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31573426, here are decompositions:

149 + 31573277 = 31573426
167 + 31573259 = 31573426
173 + 31573253 = 31573426
263 + 31573163 = 31573426
293 + 31573133 = 31573426
317 + 31573109 = 31573426
389 + 31573037 = 31573426
419 + 31573007 = 31573426

Showing the first eight; more decompositions exist.
