Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31502822, here are decompositions:

61 + 31502761 = 31502822
79 + 31502743 = 31502822
163 + 31502659 = 31502822
283 + 31502539 = 31502822
661 + 31502161 = 31502822
691 + 31502131 = 31502822
709 + 31502113 = 31502822
739 + 31502083 = 31502822

Showing the first eight; more decompositions exist.
