Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31623484, here are decompositions:

3 + 31623481 = 31623484
5 + 31623479 = 31623484
23 + 31623461 = 31623484
41 + 31623443 = 31623484
107 + 31623377 = 31623484
227 + 31623257 = 31623484
311 + 31623173 = 31623484
317 + 31623167 = 31623484

Showing the first eight; more decompositions exist.
