Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532756, here are decompositions:

7 + 31532749 = 31532756
19 + 31532737 = 31532756
97 + 31532659 = 31532756
103 + 31532653 = 31532756
163 + 31532593 = 31532756
433 + 31532323 = 31532756
487 + 31532269 = 31532756
547 + 31532209 = 31532756

Showing the first eight; more decompositions exist.
