Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31623348, here are decompositions:

5 + 31623343 = 31623348
11 + 31623337 = 31623348
137 + 31623211 = 31623348
139 + 31623209 = 31623348
149 + 31623199 = 31623348
167 + 31623181 = 31623348
179 + 31623169 = 31623348
181 + 31623167 = 31623348

Showing the first eight; more decompositions exist.
