Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8648528, here are decompositions:

139 + 8648389 = 8648528
157 + 8648371 = 8648528
181 + 8648347 = 8648528
211 + 8648317 = 8648528
277 + 8648251 = 8648528
307 + 8648221 = 8648528
337 + 8648191 = 8648528
349 + 8648179 = 8648528

Showing the first eight; more decompositions exist.
