Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469682, here are decompositions:

11 + 31469671 = 31469682
29 + 31469653 = 31469682
53 + 31469629 = 31469682
59 + 31469623 = 31469682
61 + 31469621 = 31469682
103 + 31469579 = 31469682
113 + 31469569 = 31469682
151 + 31469531 = 31469682

Showing the first eight; more decompositions exist.
