Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31502756, here are decompositions:

13 + 31502743 = 31502756
67 + 31502689 = 31502756
97 + 31502659 = 31502756
193 + 31502563 = 31502756
199 + 31502557 = 31502756
223 + 31502533 = 31502756
487 + 31502269 = 31502756
643 + 31502113 = 31502756

Showing the first eight; more decompositions exist.
