Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31538682, here are decompositions:

11 + 31538671 = 31538682
29 + 31538653 = 31538682
41 + 31538641 = 31538682
53 + 31538629 = 31538682
59 + 31538623 = 31538682
101 + 31538581 = 31538682
103 + 31538579 = 31538682
113 + 31538569 = 31538682

Showing the first eight; more decompositions exist.
