Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8648178, here are decompositions:

29 + 8648149 = 8648178
47 + 8648131 = 8648178
67 + 8648111 = 8648178
79 + 8648099 = 8648178
181 + 8647997 = 8648178
199 + 8647979 = 8648178
211 + 8647967 = 8648178
229 + 8647949 = 8648178

Showing the first eight; more decompositions exist.
