Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524518, here are decompositions:

19 + 31524499 = 31524518
241 + 31524277 = 31524518
577 + 31523941 = 31524518
601 + 31523917 = 31524518
757 + 31523761 = 31524518
769 + 31523749 = 31524518
811 + 31523707 = 31524518
859 + 31523659 = 31524518

Showing the first eight; more decompositions exist.
