Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31623814, here are decompositions:

17 + 31623797 = 31623814
83 + 31623731 = 31623814
107 + 31623707 = 31623814
113 + 31623701 = 31623814
191 + 31623623 = 31623814
197 + 31623617 = 31623814
293 + 31623521 = 31623814
317 + 31623497 = 31623814

Showing the first eight; more decompositions exist.
