Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 478288, here are decompositions:

17 + 478271 = 478288
29 + 478259 = 478288
47 + 478241 = 478288
89 + 478199 = 478288
131 + 478157 = 478288
149 + 478139 = 478288
311 + 477977 = 478288
347 + 477941 = 478288

Showing the first eight; more decompositions exist.
