Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31471170, here are decompositions:

23 + 31471147 = 31471170
47 + 31471123 = 31471170
61 + 31471109 = 31471170
79 + 31471091 = 31471170
127 + 31471043 = 31471170
139 + 31471031 = 31471170
163 + 31471007 = 31471170
173 + 31470997 = 31471170

Showing the first eight; more decompositions exist.
