Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31563358, here are decompositions:

11 + 31563347 = 31563358
89 + 31563269 = 31563358
137 + 31563221 = 31563358
149 + 31563209 = 31563358
227 + 31563131 = 31563358
269 + 31563089 = 31563358
317 + 31563041 = 31563358
509 + 31562849 = 31563358

Showing the first eight; more decompositions exist.
