Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524312, here are decompositions:

11 + 31524301 = 31524312
19 + 31524293 = 31524312
41 + 31524271 = 31524312
89 + 31524223 = 31524312
151 + 31524161 = 31524312
179 + 31524133 = 31524312
263 + 31524049 = 31524312
269 + 31524043 = 31524312

Showing the first eight; more decompositions exist.
