Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523296, here are decompositions:

3 + 31523293 = 31523296
17 + 31523279 = 31523296
29 + 31523267 = 31523296
53 + 31523243 = 31523296
59 + 31523237 = 31523296
89 + 31523207 = 31523296
197 + 31523099 = 31523296
269 + 31523027 = 31523296

Showing the first eight; more decompositions exist.
