Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31559058, here are decompositions:

7 + 31559051 = 31559058
31 + 31559027 = 31559058
61 + 31558997 = 31559058
101 + 31558957 = 31559058
131 + 31558927 = 31559058
199 + 31558859 = 31559058
211 + 31558847 = 31559058
227 + 31558831 = 31559058

Showing the first eight; more decompositions exist.
