Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482456, here are decompositions:

17 + 31482439 = 31482456
29 + 31482427 = 31482456
67 + 31482389 = 31482456
107 + 31482349 = 31482456
113 + 31482343 = 31482456
149 + 31482307 = 31482456
163 + 31482293 = 31482456
179 + 31482277 = 31482456

Showing the first eight; more decompositions exist.
