Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31530032, here are decompositions:

3 + 31530029 = 31530032
31 + 31530001 = 31530032
109 + 31529923 = 31530032
151 + 31529881 = 31530032
283 + 31529749 = 31530032
409 + 31529623 = 31530032
439 + 31529593 = 31530032
601 + 31529431 = 31530032

Showing the first eight; more decompositions exist.
