Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31563196, here are decompositions:

3 + 31563193 = 31563196
47 + 31563149 = 31563196
59 + 31563137 = 31563196
107 + 31563089 = 31563196
167 + 31563029 = 31563196
347 + 31562849 = 31563196
419 + 31562777 = 31563196
569 + 31562627 = 31563196

Showing the first eight; more decompositions exist.
