Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31492456, here are decompositions:

3 + 31492453 = 31492456
53 + 31492403 = 31492456
137 + 31492319 = 31492456
179 + 31492277 = 31492456
197 + 31492259 = 31492456
293 + 31492163 = 31492456
383 + 31492073 = 31492456
389 + 31492067 = 31492456

Showing the first eight; more decompositions exist.
