Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31475682, here are decompositions:

5 + 31475677 = 31475682
13 + 31475669 = 31475682
59 + 31475623 = 31475682
71 + 31475611 = 31475682
83 + 31475599 = 31475682
101 + 31475581 = 31475682
103 + 31475579 = 31475682
191 + 31475491 = 31475682

Showing the first eight; more decompositions exist.
