Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31502882, here are decompositions:

139 + 31502743 = 31502882
181 + 31502701 = 31502882
193 + 31502689 = 31502882
223 + 31502659 = 31502882
349 + 31502533 = 31502882
571 + 31502311 = 31502882
613 + 31502269 = 31502882
751 + 31502131 = 31502882

Showing the first eight; more decompositions exist.
