Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31471074, here are decompositions:

23 + 31471051 = 31471074
31 + 31471043 = 31471074
43 + 31471031 = 31471074
67 + 31471007 = 31471074
73 + 31471001 = 31471074
83 + 31470991 = 31471074
97 + 31470977 = 31471074
157 + 31470917 = 31471074

Showing the first eight; more decompositions exist.
