Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31623396, here are decompositions:

19 + 31623377 = 31623396
23 + 31623373 = 31623396
53 + 31623343 = 31623396
59 + 31623337 = 31623396
139 + 31623257 = 31623396
173 + 31623223 = 31623396
197 + 31623199 = 31623396
223 + 31623173 = 31623396

Showing the first eight; more decompositions exist.
