Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524506, here are decompositions:

7 + 31524499 = 31524506
37 + 31524469 = 31524506
103 + 31524403 = 31524506
163 + 31524343 = 31524506
229 + 31524277 = 31524506
283 + 31524223 = 31524506
313 + 31524193 = 31524506
373 + 31524133 = 31524506

Showing the first eight; more decompositions exist.
