Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532528, here are decompositions:

7 + 31532521 = 31532528
31 + 31532497 = 31532528
127 + 31532401 = 31532528
199 + 31532329 = 31532528
439 + 31532089 = 31532528
457 + 31532071 = 31532528
607 + 31531921 = 31532528
619 + 31531909 = 31532528

Showing the first eight; more decompositions exist.
