Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678158, here are decompositions:

11 + 8678147 = 8678158
17 + 8678141 = 8678158
29 + 8678129 = 8678158
89 + 8678069 = 8678158
101 + 8678057 = 8678158
107 + 8678051 = 8678158
131 + 8678027 = 8678158
179 + 8677979 = 8678158

Showing the first eight; more decompositions exist.
