Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601160, here are decompositions:

23 + 31601137 = 31601160
61 + 31601099 = 31601160
83 + 31601077 = 31601160
109 + 31601051 = 31601160
137 + 31601023 = 31601160
167 + 31600993 = 31601160
191 + 31600969 = 31601160
277 + 31600883 = 31601160

Showing the first eight; more decompositions exist.
