Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529252, here are decompositions:

3 + 31529249 = 31529252
103 + 31529149 = 31529252
163 + 31529089 = 31529252
199 + 31529053 = 31529252
283 + 31528969 = 31529252
409 + 31528843 = 31529252
421 + 31528831 = 31529252
439 + 31528813 = 31529252

Showing the first eight; more decompositions exist.
