Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31563046, here are decompositions:

3 + 31563043 = 31563046
5 + 31563041 = 31563046
17 + 31563029 = 31563046
59 + 31562987 = 31563046
197 + 31562849 = 31563046
269 + 31562777 = 31563046
419 + 31562627 = 31563046
443 + 31562603 = 31563046

Showing the first eight; more decompositions exist.
