Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 478308, here are decompositions:

37 + 478271 = 478308
67 + 478241 = 478308
101 + 478207 = 478308
109 + 478199 = 478308
137 + 478171 = 478308
139 + 478169 = 478308
151 + 478157 = 478308
179 + 478129 = 478308

Showing the first eight; more decompositions exist.
