Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524874, here are decompositions:

11 + 31524863 = 31524874
83 + 31524791 = 31524874
107 + 31524767 = 31524874
197 + 31524677 = 31524874
233 + 31524641 = 31524874
617 + 31524257 = 31524874
677 + 31524197 = 31524874
827 + 31524047 = 31524874

Showing the first eight; more decompositions exist.
