Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524724, here are decompositions:

3 + 31524721 = 31524724
47 + 31524677 = 31524724
83 + 31524641 = 31524724
137 + 31524587 = 31524724
191 + 31524533 = 31524724
431 + 31524293 = 31524724
467 + 31524257 = 31524724
557 + 31524167 = 31524724

Showing the first eight; more decompositions exist.
