Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8648220, here are decompositions:

29 + 8648191 = 8648220
41 + 8648179 = 8648220
71 + 8648149 = 8648220
89 + 8648131 = 8648220
107 + 8648113 = 8648220
109 + 8648111 = 8648220
127 + 8648093 = 8648220
137 + 8648083 = 8648220

Showing the first eight; more decompositions exist.
