Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606308, here are decompositions:

11 + 31606297 = 31606308
29 + 31606279 = 31606308
31 + 31606277 = 31606308
47 + 31606261 = 31606308
127 + 31606181 = 31606308
211 + 31606097 = 31606308
229 + 31606079 = 31606308
241 + 31606067 = 31606308

Showing the first eight; more decompositions exist.
