Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31623384, here are decompositions:

7 + 31623377 = 31623384
11 + 31623373 = 31623384
41 + 31623343 = 31623384
47 + 31623337 = 31623384
127 + 31623257 = 31623384
173 + 31623211 = 31623384
211 + 31623173 = 31623384
263 + 31623121 = 31623384

Showing the first eight; more decompositions exist.
