Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31559056, here are decompositions:

5 + 31559051 = 31559056
29 + 31559027 = 31559056
59 + 31558997 = 31559056
83 + 31558973 = 31559056
173 + 31558883 = 31559056
197 + 31558859 = 31559056
233 + 31558823 = 31559056
257 + 31558799 = 31559056

Showing the first eight; more decompositions exist.
