Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31566062, here are decompositions:

19 + 31566043 = 31566062
43 + 31566019 = 31566062
61 + 31566001 = 31566062
109 + 31565953 = 31566062
193 + 31565869 = 31566062
211 + 31565851 = 31566062
271 + 31565791 = 31566062
349 + 31565713 = 31566062

Showing the first eight; more decompositions exist.
