Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534056, here are decompositions:

5 + 31534051 = 31534056
23 + 31534033 = 31534056
89 + 31533967 = 31534056
97 + 31533959 = 31534056
107 + 31533949 = 31534056
137 + 31533919 = 31534056
223 + 31533833 = 31534056
227 + 31533829 = 31534056

Showing the first eight; more decompositions exist.
