Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 478456, here are decompositions:

3 + 478453 = 478456
5 + 478451 = 478456
23 + 478433 = 478456
29 + 478427 = 478456
53 + 478403 = 478456
113 + 478343 = 478456
197 + 478259 = 478456
257 + 478199 = 478456

Showing the first eight; more decompositions exist.
