Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31066, here are decompositions:

3 + 31063 = 31066
47 + 31019 = 31066
53 + 31013 = 31066
83 + 30983 = 31066
89 + 30977 = 31066
173 + 30893 = 31066
197 + 30869 = 31066
227 + 30839 = 31066

Showing the first eight; more decompositions exist.
