Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 478234, here are decompositions:

167 + 478067 = 478234
233 + 478001 = 478234
257 + 477977 = 478234
293 + 477941 = 478234
353 + 477881 = 478234
443 + 477791 = 478234
467 + 477767 = 478234
503 + 477731 = 478234

Showing the first eight; more decompositions exist.
