Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31623222, here are decompositions:

11 + 31623211 = 31623222
13 + 31623209 = 31623222
23 + 31623199 = 31623222
41 + 31623181 = 31623222
53 + 31623169 = 31623222
101 + 31623121 = 31623222
109 + 31623113 = 31623222
181 + 31623041 = 31623222

Showing the first eight; more decompositions exist.
