Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567966, here are decompositions:

5 + 31567961 = 31567966
83 + 31567883 = 31567966
107 + 31567859 = 31567966
197 + 31567769 = 31567966
257 + 31567709 = 31567966
293 + 31567673 = 31567966
317 + 31567649 = 31567966
347 + 31567619 = 31567966

Showing the first eight; more decompositions exist.
