Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8748828, here are decompositions:

7 + 8748821 = 8748828
17 + 8748811 = 8748828
41 + 8748787 = 8748828
61 + 8748767 = 8748828
89 + 8748739 = 8748828
97 + 8748731 = 8748828
181 + 8748647 = 8748828
227 + 8748601 = 8748828

Showing the first eight; more decompositions exist.
