Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8646028, here are decompositions:

11 + 8646017 = 8646028
47 + 8645981 = 8646028
101 + 8645927 = 8646028
179 + 8645849 = 8646028
239 + 8645789 = 8646028
269 + 8645759 = 8646028
359 + 8645669 = 8646028
431 + 8645597 = 8646028

Showing the first eight; more decompositions exist.
