Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524942, here are decompositions:

5 + 31524937 = 31524942
79 + 31524863 = 31524942
103 + 31524839 = 31524942
149 + 31524793 = 31524942
151 + 31524791 = 31524942
179 + 31524763 = 31524942
269 + 31524673 = 31524942
373 + 31524569 = 31524942

Showing the first eight; more decompositions exist.
