Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31500662, here are decompositions:

3 + 31500659 = 31500662
13 + 31500649 = 31500662
73 + 31500589 = 31500662
103 + 31500559 = 31500662
199 + 31500463 = 31500662
211 + 31500451 = 31500662
283 + 31500379 = 31500662
673 + 31499989 = 31500662

Showing the first eight; more decompositions exist.
