Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524112, here are decompositions:

5 + 31524107 = 31524112
89 + 31524023 = 31524112
101 + 31524011 = 31524112
173 + 31523939 = 31524112
311 + 31523801 = 31524112
359 + 31523753 = 31524112
443 + 31523669 = 31524112
461 + 31523651 = 31524112

Showing the first eight; more decompositions exist.
