Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31471086, here are decompositions:

7 + 31471079 = 31471086
43 + 31471043 = 31471086
79 + 31471007 = 31471086
89 + 31470997 = 31471086
109 + 31470977 = 31471086
173 + 31470913 = 31471086
197 + 31470889 = 31471086
223 + 31470863 = 31471086

Showing the first eight; more decompositions exist.
