Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31492324, here are decompositions:

5 + 31492319 = 31492324
47 + 31492277 = 31492324
167 + 31492157 = 31492324
233 + 31492091 = 31492324
251 + 31492073 = 31492324
257 + 31492067 = 31492324
263 + 31492061 = 31492324
293 + 31492031 = 31492324

Showing the first eight; more decompositions exist.
