Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529528, here are decompositions:

7 + 31529521 = 31529528
97 + 31529431 = 31529528
181 + 31529347 = 31529528
271 + 31529257 = 31529528
379 + 31529149 = 31529528
421 + 31529107 = 31529528
439 + 31529089 = 31529528
619 + 31528909 = 31529528

Showing the first eight; more decompositions exist.
