Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31600474, here are decompositions:

23 + 31600451 = 31600474
53 + 31600421 = 31600474
167 + 31600307 = 31600474
173 + 31600301 = 31600474
197 + 31600277 = 31600474
281 + 31600193 = 31600474
317 + 31600157 = 31600474
431 + 31600043 = 31600474

Showing the first eight; more decompositions exist.
