Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607298, here are decompositions:

5 + 31607293 = 31607298
7 + 31607291 = 31607298
17 + 31607281 = 31607298
61 + 31607237 = 31607298
71 + 31607227 = 31607298
97 + 31607201 = 31607298
197 + 31607101 = 31607298
211 + 31607087 = 31607298

Showing the first eight; more decompositions exist.
