Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678328, here are decompositions:

5 + 8678323 = 8678328
17 + 8678311 = 8678328
149 + 8678179 = 8678328
167 + 8678161 = 8678328
179 + 8678149 = 8678328
181 + 8678147 = 8678328
199 + 8678129 = 8678328
271 + 8678057 = 8678328

Showing the first eight; more decompositions exist.
