Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524994, here are decompositions:

3 + 31524991 = 31524994
5 + 31524989 = 31524994
101 + 31524893 = 31524994
131 + 31524863 = 31524994
197 + 31524797 = 31524994
227 + 31524767 = 31524994
317 + 31524677 = 31524994
353 + 31524641 = 31524994

Showing the first eight; more decompositions exist.
