Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532656, here are decompositions:

3 + 31532653 = 31532656
17 + 31532639 = 31532656
59 + 31532597 = 31532656
83 + 31532573 = 31532656
149 + 31532507 = 31532656
167 + 31532489 = 31532656
179 + 31532477 = 31532656
227 + 31532429 = 31532656

Showing the first eight; more decompositions exist.
