Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 478258, here are decompositions:

5 + 478253 = 478258
17 + 478241 = 478258
59 + 478199 = 478258
89 + 478169 = 478258
101 + 478157 = 478258
191 + 478067 = 478258
257 + 478001 = 478258
281 + 477977 = 478258

Showing the first eight; more decompositions exist.
