Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31563466, here are decompositions:

3 + 31563463 = 31563466
23 + 31563443 = 31563466
89 + 31563377 = 31563466
107 + 31563359 = 31563466
197 + 31563269 = 31563466
257 + 31563209 = 31563466
317 + 31563149 = 31563466
479 + 31562987 = 31563466

Showing the first eight; more decompositions exist.
