Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606366, here are decompositions:

23 + 31606343 = 31606366
47 + 31606319 = 31606366
53 + 31606313 = 31606366
83 + 31606283 = 31606366
89 + 31606277 = 31606366
179 + 31606187 = 31606366
269 + 31606097 = 31606366
317 + 31606049 = 31606366

Showing the first eight; more decompositions exist.
