Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31566132, here are decompositions:

53 + 31566079 = 31566132
71 + 31566061 = 31566132
89 + 31566043 = 31566132
113 + 31566019 = 31566132
131 + 31566001 = 31566132
139 + 31565993 = 31566132
151 + 31565981 = 31566132
163 + 31565969 = 31566132

Showing the first eight; more decompositions exist.
