Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31502682, here are decompositions:

23 + 31502659 = 31502682
149 + 31502533 = 31502682
193 + 31502489 = 31502682
199 + 31502483 = 31502682
223 + 31502459 = 31502682
241 + 31502441 = 31502682
251 + 31502431 = 31502682
311 + 31502371 = 31502682

Showing the first eight; more decompositions exist.
