Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31563376, here are decompositions:

17 + 31563359 = 31563376
29 + 31563347 = 31563376
107 + 31563269 = 31563376
167 + 31563209 = 31563376
227 + 31563149 = 31563376
239 + 31563137 = 31563376
347 + 31563029 = 31563376
389 + 31562987 = 31563376

Showing the first eight; more decompositions exist.
