Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529522, here are decompositions:

43 + 31529479 = 31529522
109 + 31529413 = 31529522
163 + 31529359 = 31529522
373 + 31529149 = 31529522
433 + 31529089 = 31529522
613 + 31528909 = 31529522
691 + 31528831 = 31529522
709 + 31528813 = 31529522

Showing the first eight; more decompositions exist.
