Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31559134, here are decompositions:

3 + 31559131 = 31559134
41 + 31559093 = 31559134
53 + 31559081 = 31559134
83 + 31559051 = 31559134
107 + 31559027 = 31559134
137 + 31558997 = 31559134
251 + 31558883 = 31559134
311 + 31558823 = 31559134

Showing the first eight; more decompositions exist.
