Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524090, here are decompositions:

41 + 31524049 = 31524090
43 + 31524047 = 31524090
47 + 31524043 = 31524090
67 + 31524023 = 31524090
79 + 31524011 = 31524090
137 + 31523953 = 31524090
149 + 31523941 = 31524090
151 + 31523939 = 31524090

Showing the first eight; more decompositions exist.
