Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31566060, here are decompositions:

17 + 31566043 = 31566060
41 + 31566019 = 31566060
47 + 31566013 = 31566060
59 + 31566001 = 31566060
67 + 31565993 = 31566060
79 + 31565981 = 31566060
89 + 31565971 = 31566060
107 + 31565953 = 31566060

Showing the first eight; more decompositions exist.
