Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524104, here are decompositions:

13 + 31524091 = 31524104
61 + 31524043 = 31524104
151 + 31523953 = 31524104
163 + 31523941 = 31524104
223 + 31523881 = 31524104
397 + 31523707 = 31524104
457 + 31523647 = 31524104
631 + 31523473 = 31524104

Showing the first eight; more decompositions exist.
