Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524126, here are decompositions:

19 + 31524107 = 31524126
79 + 31524047 = 31524126
83 + 31524043 = 31524126
103 + 31524023 = 31524126
113 + 31524013 = 31524126
173 + 31523953 = 31524126
373 + 31523753 = 31524126
419 + 31523707 = 31524126

Showing the first eight; more decompositions exist.
