Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8648128, here are decompositions:

17 + 8648111 = 8648128
29 + 8648099 = 8648128
131 + 8647997 = 8648128
149 + 8647979 = 8648128
179 + 8647949 = 8648128
191 + 8647937 = 8648128
239 + 8647889 = 8648128
311 + 8647817 = 8648128

Showing the first eight; more decompositions exist.
