Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31471150, here are decompositions:

3 + 31471147 = 31471150
41 + 31471109 = 31471150
59 + 31471091 = 31471150
71 + 31471079 = 31471150
107 + 31471043 = 31471150
149 + 31471001 = 31471150
173 + 31470977 = 31471150
197 + 31470953 = 31471150

Showing the first eight; more decompositions exist.
