Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31623914, here are decompositions:

13 + 31623901 = 31623914
97 + 31623817 = 31623914
193 + 31623721 = 31623914
211 + 31623703 = 31623914
307 + 31623607 = 31623914
433 + 31623481 = 31623914
541 + 31623373 = 31623914
571 + 31623343 = 31623914

Showing the first eight; more decompositions exist.
