Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31564276, here are decompositions:

5 + 31564271 = 31564276
47 + 31564229 = 31564276
113 + 31564163 = 31564276
137 + 31564139 = 31564276
173 + 31564103 = 31564276
197 + 31564079 = 31564276
347 + 31563929 = 31564276
449 + 31563827 = 31564276

Showing the first eight; more decompositions exist.
