Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544008, here are decompositions:

11 + 31543997 = 31544008
17 + 31543991 = 31544008
29 + 31543979 = 31544008
47 + 31543961 = 31544008
101 + 31543907 = 31544008
131 + 31543877 = 31544008
137 + 31543871 = 31544008
149 + 31543859 = 31544008

Showing the first eight; more decompositions exist.
