Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606330, here are decompositions:

11 + 31606319 = 31606330
17 + 31606313 = 31606330
47 + 31606283 = 31606330
53 + 31606277 = 31606330
149 + 31606181 = 31606330
233 + 31606097 = 31606330
251 + 31606079 = 31606330
263 + 31606067 = 31606330

Showing the first eight; more decompositions exist.
