Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524480, here are decompositions:

11 + 31524469 = 31524480
61 + 31524419 = 31524480
137 + 31524343 = 31524480
149 + 31524331 = 31524480
179 + 31524301 = 31524480
223 + 31524257 = 31524480
257 + 31524223 = 31524480
283 + 31524197 = 31524480

Showing the first eight; more decompositions exist.
