Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678210, here are decompositions:

7 + 8678203 = 8678210
31 + 8678179 = 8678210
61 + 8678149 = 8678210
97 + 8678113 = 8678210
127 + 8678083 = 8678210
157 + 8678053 = 8678210
181 + 8678029 = 8678210
199 + 8678011 = 8678210

Showing the first eight; more decompositions exist.
