Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8748644, here are decompositions:

43 + 8748601 = 8748644
61 + 8748583 = 8748644
181 + 8748463 = 8748644
241 + 8748403 = 8748644
277 + 8748367 = 8748644
283 + 8748361 = 8748644
313 + 8748331 = 8748644
367 + 8748277 = 8748644

Showing the first eight; more decompositions exist.
