Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524972, here are decompositions:

5 + 31524967 = 31524972
79 + 31524893 = 31524972
109 + 31524863 = 31524972
163 + 31524809 = 31524972
179 + 31524793 = 31524972
181 + 31524791 = 31524972
251 + 31524721 = 31524972
331 + 31524641 = 31524972

Showing the first eight; more decompositions exist.
