Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31471056, here are decompositions:

5 + 31471051 = 31471056
13 + 31471043 = 31471056
59 + 31470997 = 31471056
79 + 31470977 = 31471056
103 + 31470953 = 31471056
139 + 31470917 = 31471056
167 + 31470889 = 31471056
193 + 31470863 = 31471056

Showing the first eight; more decompositions exist.
