Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31559074, here are decompositions:

3 + 31559071 = 31559074
5 + 31559069 = 31559074
23 + 31559051 = 31559074
47 + 31559027 = 31559074
101 + 31558973 = 31559074
191 + 31558883 = 31559074
227 + 31558847 = 31559074
251 + 31558823 = 31559074

Showing the first eight; more decompositions exist.
