Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8748408, here are decompositions:

5 + 8748403 = 8748408
41 + 8748367 = 8748408
47 + 8748361 = 8748408
79 + 8748329 = 8748408
127 + 8748281 = 8748408
131 + 8748277 = 8748408
199 + 8748209 = 8748408
241 + 8748167 = 8748408

Showing the first eight; more decompositions exist.
