Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31471066, here are decompositions:

23 + 31471043 = 31471066
59 + 31471007 = 31471066
89 + 31470977 = 31471066
113 + 31470953 = 31471066
149 + 31470917 = 31471066
197 + 31470869 = 31471066
233 + 31470833 = 31471066
239 + 31470827 = 31471066

Showing the first eight; more decompositions exist.
