Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31623716, here are decompositions:

13 + 31623703 = 31623716
109 + 31623607 = 31623716
127 + 31623589 = 31623716
193 + 31623523 = 31623716
277 + 31623439 = 31623716
373 + 31623343 = 31623716
379 + 31623337 = 31623716
547 + 31623169 = 31623716

Showing the first eight; more decompositions exist.
