Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31475694, here are decompositions:

11 + 31475683 = 31475694
13 + 31475681 = 31475694
17 + 31475677 = 31475694
71 + 31475623 = 31475694
83 + 31475611 = 31475694
97 + 31475597 = 31475694
113 + 31475581 = 31475694
223 + 31475471 = 31475694

Showing the first eight; more decompositions exist.
