Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31563382, here are decompositions:

5 + 31563377 = 31563382
23 + 31563359 = 31563382
113 + 31563269 = 31563382
173 + 31563209 = 31563382
233 + 31563149 = 31563382
251 + 31563131 = 31563382
293 + 31563089 = 31563382
353 + 31563029 = 31563382

Showing the first eight; more decompositions exist.
