Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678340, here are decompositions:

7 + 8678333 = 8678340
17 + 8678323 = 8678340
29 + 8678311 = 8678340
103 + 8678237 = 8678340
127 + 8678213 = 8678340
137 + 8678203 = 8678340
179 + 8678161 = 8678340
191 + 8678149 = 8678340

Showing the first eight; more decompositions exist.
