Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606384, here are decompositions:

3 + 31606381 = 31606384
11 + 31606373 = 31606384
41 + 31606343 = 31606384
53 + 31606331 = 31606384
71 + 31606313 = 31606384
101 + 31606283 = 31606384
107 + 31606277 = 31606384
197 + 31606187 = 31606384

Showing the first eight; more decompositions exist.
