Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31563526, here are decompositions:

83 + 31563443 = 31563526
149 + 31563377 = 31563526
167 + 31563359 = 31563526
179 + 31563347 = 31563526
257 + 31563269 = 31563526
317 + 31563209 = 31563526
389 + 31563137 = 31563526
677 + 31562849 = 31563526

Showing the first eight; more decompositions exist.
