Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524332, here are decompositions:

31 + 31524301 = 31524332
61 + 31524271 = 31524332
109 + 31524223 = 31524332
139 + 31524193 = 31524332
199 + 31524133 = 31524332
241 + 31524091 = 31524332
283 + 31524049 = 31524332
379 + 31523953 = 31524332

Showing the first eight; more decompositions exist.
