Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524422, here are decompositions:

3 + 31524419 = 31524422
19 + 31524403 = 31524422
79 + 31524343 = 31524422
151 + 31524271 = 31524422
199 + 31524223 = 31524422
229 + 31524193 = 31524422
331 + 31524091 = 31524422
373 + 31524049 = 31524422

Showing the first eight; more decompositions exist.
