Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8648148, here are decompositions:

17 + 8648131 = 8648148
37 + 8648111 = 8648148
151 + 8647997 = 8648148
181 + 8647967 = 8648148
199 + 8647949 = 8648148
211 + 8647937 = 8648148
251 + 8647897 = 8648148
269 + 8647879 = 8648148

Showing the first eight; more decompositions exist.
