Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31493176, here are decompositions:

5 + 31493171 = 31493176
23 + 31493153 = 31493176
107 + 31493069 = 31493176
137 + 31493039 = 31493176
167 + 31493009 = 31493176
179 + 31492997 = 31493176
233 + 31492943 = 31493176
269 + 31492907 = 31493176

Showing the first eight; more decompositions exist.
