Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529422, here are decompositions:

101 + 31529321 = 31529422
149 + 31529273 = 31529422
173 + 31529249 = 31529422
179 + 31529243 = 31529422
569 + 31528853 = 31529422
599 + 31528823 = 31529422
809 + 31528613 = 31529422
863 + 31528559 = 31529422

Showing the first eight; more decompositions exist.
