Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524124, here are decompositions:

17 + 31524107 = 31524124
101 + 31524023 = 31524124
113 + 31524011 = 31524124
491 + 31523633 = 31524124
587 + 31523537 = 31524124
647 + 31523477 = 31524124
683 + 31523441 = 31524124
743 + 31523381 = 31524124

Showing the first eight; more decompositions exist.
