Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31623658, here are decompositions:

41 + 31623617 = 31623658
137 + 31623521 = 31623658
149 + 31623509 = 31623658
167 + 31623491 = 31623658
179 + 31623479 = 31623658
197 + 31623461 = 31623658
281 + 31623377 = 31623658
401 + 31623257 = 31623658

Showing the first eight; more decompositions exist.
