Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601166, here are decompositions:

29 + 31601137 = 31601166
67 + 31601099 = 31601166
83 + 31601083 = 31601166
89 + 31601077 = 31601166
173 + 31600993 = 31601166
197 + 31600969 = 31601166
283 + 31600883 = 31601166
307 + 31600859 = 31601166

Showing the first eight; more decompositions exist.
