Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31566126, here are decompositions:

43 + 31566083 = 31566126
47 + 31566079 = 31566126
83 + 31566043 = 31566126
107 + 31566019 = 31566126
113 + 31566013 = 31566126
157 + 31565969 = 31566126
173 + 31565953 = 31566126
197 + 31565929 = 31566126

Showing the first eight; more decompositions exist.
