Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523324, here are decompositions:

31 + 31523293 = 31523324
73 + 31523251 = 31523324
97 + 31523227 = 31523324
103 + 31523221 = 31523324
163 + 31523161 = 31523324
181 + 31523143 = 31523324
193 + 31523131 = 31523324
211 + 31523113 = 31523324

Showing the first eight; more decompositions exist.
