Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31564314, here are decompositions:

43 + 31564271 = 31564314
53 + 31564261 = 31564314
71 + 31564243 = 31564314
73 + 31564241 = 31564314
107 + 31564207 = 31564314
151 + 31564163 = 31564314
157 + 31564157 = 31564314
167 + 31564147 = 31564314

Showing the first eight; more decompositions exist.
