Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596040, here are decompositions:

11 + 31596029 = 31596040
71 + 31595969 = 31596040
167 + 31595873 = 31596040
173 + 31595867 = 31596040
233 + 31595807 = 31596040
257 + 31595783 = 31596040
263 + 31595777 = 31596040
269 + 31595771 = 31596040

Showing the first eight; more decompositions exist.
