Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524304, here are decompositions:

3 + 31524301 = 31524304
11 + 31524293 = 31524304
47 + 31524257 = 31524304
107 + 31524197 = 31524304
137 + 31524167 = 31524304
197 + 31524107 = 31524304
257 + 31524047 = 31524304
281 + 31524023 = 31524304

Showing the first eight; more decompositions exist.
