Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8748208, here are decompositions:

5 + 8748203 = 8748208
17 + 8748191 = 8748208
41 + 8748167 = 8748208
47 + 8748161 = 8748208
71 + 8748137 = 8748208
191 + 8748017 = 8748208
197 + 8748011 = 8748208
251 + 8747957 = 8748208

Showing the first eight; more decompositions exist.
