Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31548966, here are decompositions:

5 + 31548961 = 31548966
13 + 31548953 = 31548966
109 + 31548857 = 31548966
149 + 31548817 = 31548966
199 + 31548767 = 31548966
223 + 31548743 = 31548966
227 + 31548739 = 31548966
233 + 31548733 = 31548966

Showing the first eight; more decompositions exist.
