Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31566048, here are decompositions:

5 + 31566043 = 31566048
29 + 31566019 = 31566048
47 + 31566001 = 31566048
67 + 31565981 = 31566048
79 + 31565969 = 31566048
131 + 31565917 = 31566048
179 + 31565869 = 31566048
197 + 31565851 = 31566048

Showing the first eight; more decompositions exist.
