Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31623474, here are decompositions:

13 + 31623461 = 31623474
31 + 31623443 = 31623474
53 + 31623421 = 31623474
97 + 31623377 = 31623474
101 + 31623373 = 31623474
131 + 31623343 = 31623474
137 + 31623337 = 31623474
251 + 31623223 = 31623474

Showing the first eight; more decompositions exist.
