Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31458474, here are decompositions:

23 + 31458451 = 31458474
37 + 31458437 = 31458474
43 + 31458431 = 31458474
71 + 31458403 = 31458474
97 + 31458377 = 31458474
101 + 31458373 = 31458474
163 + 31458311 = 31458474
197 + 31458277 = 31458474

Showing the first eight; more decompositions exist.
