Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524162, here are decompositions:

29 + 31524133 = 31524162
71 + 31524091 = 31524162
113 + 31524049 = 31524162
139 + 31524023 = 31524162
149 + 31524013 = 31524162
151 + 31524011 = 31524162
223 + 31523939 = 31524162
281 + 31523881 = 31524162

Showing the first eight; more decompositions exist.
