Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31559344, here are decompositions:

23 + 31559321 = 31559344
137 + 31559207 = 31559344
251 + 31559093 = 31559344
263 + 31559081 = 31559344
293 + 31559051 = 31559344
317 + 31559027 = 31559344
347 + 31558997 = 31559344
461 + 31558883 = 31559344

Showing the first eight; more decompositions exist.
