Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8648238, here are decompositions:

17 + 8648221 = 8648238
47 + 8648191 = 8648238
59 + 8648179 = 8648238
89 + 8648149 = 8648238
107 + 8648131 = 8648238
127 + 8648111 = 8648238
139 + 8648099 = 8648238
241 + 8647997 = 8648238

Showing the first eight; more decompositions exist.
