Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31564326, here are decompositions:

5 + 31564321 = 31564326
83 + 31564243 = 31564326
89 + 31564237 = 31564326
97 + 31564229 = 31564326
163 + 31564163 = 31564326
179 + 31564147 = 31564326
193 + 31564133 = 31564326
197 + 31564129 = 31564326

Showing the first eight; more decompositions exist.
