Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31564358, here are decompositions:

31 + 31564327 = 31564358
37 + 31564321 = 31564358
97 + 31564261 = 31564358
109 + 31564249 = 31564358
151 + 31564207 = 31564358
211 + 31564147 = 31564358
229 + 31564129 = 31564358
307 + 31564051 = 31564358

Showing the first eight; more decompositions exist.
