Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606374, here are decompositions:

5 + 31606369 = 31606374
31 + 31606343 = 31606374
43 + 31606331 = 31606374
61 + 31606313 = 31606374
97 + 31606277 = 31606374
113 + 31606261 = 31606374
193 + 31606181 = 31606374
277 + 31606097 = 31606374

Showing the first eight; more decompositions exist.
