Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31623406, here are decompositions:

29 + 31623377 = 31623406
149 + 31623257 = 31623406
197 + 31623209 = 31623406
233 + 31623173 = 31623406
239 + 31623167 = 31623406
293 + 31623113 = 31623406
359 + 31623047 = 31623406
383 + 31623023 = 31623406

Showing the first eight; more decompositions exist.
