Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31563348, here are decompositions:

71 + 31563277 = 31563348
79 + 31563269 = 31563348
127 + 31563221 = 31563348
139 + 31563209 = 31563348
199 + 31563149 = 31563348
211 + 31563137 = 31563348
307 + 31563041 = 31563348
317 + 31563031 = 31563348

Showing the first eight; more decompositions exist.
