Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678178, here are decompositions:

17 + 8678161 = 8678178
29 + 8678149 = 8678178
31 + 8678147 = 8678178
37 + 8678141 = 8678178
97 + 8678081 = 8678178
109 + 8678069 = 8678178
127 + 8678051 = 8678178
139 + 8678039 = 8678178

Showing the first eight; more decompositions exist.
