Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534074, here are decompositions:

7 + 31534067 = 31534074
17 + 31534057 = 31534074
23 + 31534051 = 31534074
41 + 31534033 = 31534074
107 + 31533967 = 31534074
151 + 31533923 = 31534074
163 + 31533911 = 31534074
227 + 31533847 = 31534074

Showing the first eight; more decompositions exist.
