Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31470956, here are decompositions:

3 + 31470953 = 31470956
43 + 31470913 = 31470956
67 + 31470889 = 31470956
103 + 31470853 = 31470956
109 + 31470847 = 31470956
157 + 31470799 = 31470956
163 + 31470793 = 31470956
337 + 31470619 = 31470956

Showing the first eight; more decompositions exist.
