Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524222, here are decompositions:

29 + 31524193 = 31524222
61 + 31524161 = 31524222
89 + 31524133 = 31524222
131 + 31524091 = 31524222
173 + 31524049 = 31524222
179 + 31524043 = 31524222
199 + 31524023 = 31524222
211 + 31524011 = 31524222

Showing the first eight; more decompositions exist.
