Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 478284, here are decompositions:

11 + 478273 = 478284
13 + 478271 = 478284
31 + 478253 = 478284
41 + 478243 = 478284
43 + 478241 = 478284
71 + 478213 = 478284
113 + 478171 = 478284
127 + 478157 = 478284

Showing the first eight; more decompositions exist.
