Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523332, here are decompositions:

3 + 31523329 = 31523332
23 + 31523309 = 31523332
53 + 31523279 = 31523332
89 + 31523243 = 31523332
101 + 31523231 = 31523332
131 + 31523201 = 31523332
233 + 31523099 = 31523332
251 + 31523081 = 31523332

Showing the first eight; more decompositions exist.
