Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607682, here are decompositions:

11 + 31607671 = 31607682
53 + 31607629 = 31607682
83 + 31607599 = 31607682
101 + 31607581 = 31607682
103 + 31607579 = 31607682
131 + 31607551 = 31607682
151 + 31607531 = 31607682
179 + 31607503 = 31607682

Showing the first eight; more decompositions exist.
