Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8651178, here are decompositions:

17 + 8651161 = 8651178
37 + 8651141 = 8651178
59 + 8651119 = 8651178
61 + 8651117 = 8651178
127 + 8651051 = 8651178
131 + 8651047 = 8651178
139 + 8651039 = 8651178
181 + 8650997 = 8651178

Showing the first eight; more decompositions exist.
