Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529312, here are decompositions:

43 + 31529269 = 31529312
163 + 31529149 = 31529312
223 + 31529089 = 31529312
499 + 31528813 = 31529312
571 + 31528741 = 31529312
643 + 31528669 = 31529312
691 + 31528621 = 31529312
733 + 31528579 = 31529312

Showing the first eight; more decompositions exist.
