Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678166, here are decompositions:

5 + 8678161 = 8678166
17 + 8678149 = 8678166
19 + 8678147 = 8678166
37 + 8678129 = 8678166
53 + 8678113 = 8678166
73 + 8678093 = 8678166
83 + 8678083 = 8678166
97 + 8678069 = 8678166

Showing the first eight; more decompositions exist.
