Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 478198, here are decompositions:

29 + 478169 = 478198
41 + 478157 = 478198
59 + 478139 = 478198
131 + 478067 = 478198
197 + 478001 = 478198
251 + 477947 = 478198
257 + 477941 = 478198
317 + 477881 = 478198

Showing the first eight; more decompositions exist.
