Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8648522, here are decompositions:

109 + 8648413 = 8648522
151 + 8648371 = 8648522
199 + 8648323 = 8648522
271 + 8648251 = 8648522
283 + 8648239 = 8648522
331 + 8648191 = 8648522
373 + 8648149 = 8648522
409 + 8648113 = 8648522

Showing the first eight; more decompositions exist.
