Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8748824, here are decompositions:

3 + 8748821 = 8748824
13 + 8748811 = 8748824
37 + 8748787 = 8748824
151 + 8748673 = 8748824
181 + 8748643 = 8748824
223 + 8748601 = 8748824
241 + 8748583 = 8748824
421 + 8748403 = 8748824

Showing the first eight; more decompositions exist.
