Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31559116, here are decompositions:

23 + 31559093 = 31559116
47 + 31559069 = 31559116
89 + 31559027 = 31559116
233 + 31558883 = 31559116
257 + 31558859 = 31559116
269 + 31558847 = 31559116
293 + 31558823 = 31559116
317 + 31558799 = 31559116

Showing the first eight; more decompositions exist.
