Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31586176, here are decompositions:

5 + 31586171 = 31586176
29 + 31586147 = 31586176
173 + 31586003 = 31586176
179 + 31585997 = 31586176
197 + 31585979 = 31586176
239 + 31585937 = 31586176
353 + 31585823 = 31586176
359 + 31585817 = 31586176

Showing the first eight; more decompositions exist.
