Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 478338, here are decompositions:

17 + 478321 = 478338
67 + 478271 = 478338
79 + 478259 = 478338
97 + 478241 = 478338
131 + 478207 = 478338
139 + 478199 = 478338
149 + 478189 = 478338
167 + 478171 = 478338

Showing the first eight; more decompositions exist.
