Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 478454, here are decompositions:

3 + 478451 = 478454
13 + 478441 = 478454
37 + 478417 = 478454
43 + 478411 = 478454
103 + 478351 = 478454
181 + 478273 = 478454
211 + 478243 = 478454
241 + 478213 = 478454

Showing the first eight; more decompositions exist.
