Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529392, here are decompositions:

71 + 31529321 = 31529392
113 + 31529279 = 31529392
149 + 31529243 = 31529392
173 + 31529219 = 31529392
179 + 31529213 = 31529392
311 + 31529081 = 31529392
569 + 31528823 = 31529392
641 + 31528751 = 31529392

Showing the first eight; more decompositions exist.
