Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524308, here are decompositions:

7 + 31524301 = 31524308
31 + 31524277 = 31524308
37 + 31524271 = 31524308
367 + 31523941 = 31524308
457 + 31523851 = 31524308
547 + 31523761 = 31524308
601 + 31523707 = 31524308
661 + 31523647 = 31524308

Showing the first eight; more decompositions exist.
