Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524554, here are decompositions:

13 + 31524541 = 31524554
31 + 31524523 = 31524554
37 + 31524517 = 31524554
151 + 31524403 = 31524554
211 + 31524343 = 31524554
223 + 31524331 = 31524554
277 + 31524277 = 31524554
283 + 31524271 = 31524554

Showing the first eight; more decompositions exist.
