Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523312, here are decompositions:

3 + 31523309 = 31523312
19 + 31523293 = 31523312
61 + 31523251 = 31523312
103 + 31523209 = 31523312
151 + 31523161 = 31523312
181 + 31523131 = 31523312
193 + 31523119 = 31523312
199 + 31523113 = 31523312

Showing the first eight; more decompositions exist.
