Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31623306, here are decompositions:

83 + 31623223 = 31623306
97 + 31623209 = 31623306
107 + 31623199 = 31623306
137 + 31623169 = 31623306
139 + 31623167 = 31623306
193 + 31623113 = 31623306
283 + 31623023 = 31623306
347 + 31622959 = 31623306

Showing the first eight; more decompositions exist.
