Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547694, here are decompositions:

11 + 31547683 = 31547694
23 + 31547671 = 31547694
53 + 31547641 = 31547694
103 + 31547591 = 31547694
137 + 31547557 = 31547694
163 + 31547531 = 31547694
223 + 31547471 = 31547694
281 + 31547413 = 31547694

Showing the first eight; more decompositions exist.
