Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31566116, here are decompositions:

37 + 31566079 = 31566116
73 + 31566043 = 31566116
97 + 31566019 = 31566116
103 + 31566013 = 31566116
163 + 31565953 = 31566116
199 + 31565917 = 31566116
229 + 31565887 = 31566116
313 + 31565803 = 31566116

Showing the first eight; more decompositions exist.
