Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524042, here are decompositions:

19 + 31524023 = 31524042
29 + 31524013 = 31524042
31 + 31524011 = 31524042
89 + 31523953 = 31524042
101 + 31523941 = 31524042
103 + 31523939 = 31524042
191 + 31523851 = 31524042
239 + 31523803 = 31524042

Showing the first eight; more decompositions exist.
