Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31623846, here are decompositions:

29 + 31623817 = 31623846
139 + 31623707 = 31623846
179 + 31623667 = 31623846
223 + 31623623 = 31623846
229 + 31623617 = 31623846
239 + 31623607 = 31623846
257 + 31623589 = 31623846
337 + 31623509 = 31623846

Showing the first eight; more decompositions exist.
