Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524428, here are decompositions:

97 + 31524331 = 31524428
127 + 31524301 = 31524428
151 + 31524277 = 31524428
157 + 31524271 = 31524428
337 + 31524091 = 31524428
379 + 31524049 = 31524428
487 + 31523941 = 31524428
547 + 31523881 = 31524428

Showing the first eight; more decompositions exist.
