Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 478450, here are decompositions:

17 + 478433 = 478450
23 + 478427 = 478450
29 + 478421 = 478450
47 + 478403 = 478450
59 + 478391 = 478450
107 + 478343 = 478450
179 + 478271 = 478450
191 + 478259 = 478450

Showing the first eight; more decompositions exist.
