Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606348, here are decompositions:

5 + 31606343 = 31606348
17 + 31606331 = 31606348
29 + 31606319 = 31606348
71 + 31606277 = 31606348
167 + 31606181 = 31606348
251 + 31606097 = 31606348
269 + 31606079 = 31606348
281 + 31606067 = 31606348

Showing the first eight; more decompositions exist.
