Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31563048, here are decompositions:

5 + 31563043 = 31563048
7 + 31563041 = 31563048
17 + 31563031 = 31563048
19 + 31563029 = 31563048
47 + 31563001 = 31563048
61 + 31562987 = 31563048
67 + 31562981 = 31563048
89 + 31562959 = 31563048

Showing the first eight; more decompositions exist.
