Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524040, here are decompositions:

17 + 31524023 = 31524040
29 + 31524011 = 31524040
101 + 31523939 = 31524040
239 + 31523801 = 31524040
389 + 31523651 = 31524040
461 + 31523579 = 31524040
503 + 31523537 = 31524040
563 + 31523477 = 31524040

Showing the first eight; more decompositions exist.
