Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606360, here are decompositions:

17 + 31606343 = 31606360
29 + 31606331 = 31606360
41 + 31606319 = 31606360
47 + 31606313 = 31606360
83 + 31606277 = 31606360
173 + 31606187 = 31606360
179 + 31606181 = 31606360
263 + 31606097 = 31606360

Showing the first eight; more decompositions exist.
