Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8648648, here are decompositions:

97 + 8648551 = 8648648
277 + 8648371 = 8648648
331 + 8648317 = 8648648
397 + 8648251 = 8648648
409 + 8648239 = 8648648
457 + 8648191 = 8648648
499 + 8648149 = 8648648
751 + 8647897 = 8648648

Showing the first eight; more decompositions exist.
