Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 478158, here are decompositions:

19 + 478139 = 478158
29 + 478129 = 478158
47 + 478111 = 478158
59 + 478099 = 478158
71 + 478087 = 478158
89 + 478069 = 478158
157 + 478001 = 478158
167 + 477991 = 478158

Showing the first eight; more decompositions exist.
