Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31566276, here are decompositions:

29 + 31566247 = 31566276
107 + 31566169 = 31566276
109 + 31566167 = 31566276
139 + 31566137 = 31566276
193 + 31566083 = 31566276
197 + 31566079 = 31566276
199 + 31566077 = 31566276
233 + 31566043 = 31566276

Showing the first eight; more decompositions exist.
