Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8672178, here are decompositions:

17 + 8672161 = 8672178
61 + 8672117 = 8672178
79 + 8672099 = 8672178
131 + 8672047 = 8672178
191 + 8671987 = 8672178
197 + 8671981 = 8672178
199 + 8671979 = 8672178
211 + 8671967 = 8672178

Showing the first eight; more decompositions exist.
