Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8648218, here are decompositions:

107 + 8648111 = 8648218
239 + 8647979 = 8648218
251 + 8647967 = 8648218
269 + 8647949 = 8648218
281 + 8647937 = 8648218
401 + 8647817 = 8648218
479 + 8647739 = 8648218
521 + 8647697 = 8648218

Showing the first eight; more decompositions exist.
