Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 478446, here are decompositions:

5 + 478441 = 478446
13 + 478433 = 478446
19 + 478427 = 478446
29 + 478417 = 478446
43 + 478403 = 478446
47 + 478399 = 478446
103 + 478343 = 478446
107 + 478339 = 478446

Showing the first eight; more decompositions exist.
