Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8648028, here are decompositions:

31 + 8647997 = 8648028
61 + 8647967 = 8648028
79 + 8647949 = 8648028
101 + 8647927 = 8648028
131 + 8647897 = 8648028
139 + 8647889 = 8648028
149 + 8647879 = 8648028
211 + 8647817 = 8648028

Showing the first eight; more decompositions exist.
