Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606324, here are decompositions:

5 + 31606319 = 31606324
11 + 31606313 = 31606324
41 + 31606283 = 31606324
47 + 31606277 = 31606324
137 + 31606187 = 31606324
227 + 31606097 = 31606324
257 + 31606067 = 31606324
263 + 31606061 = 31606324

Showing the first eight; more decompositions exist.
