Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8748400, here are decompositions:

41 + 8748359 = 8748400
71 + 8748329 = 8748400
113 + 8748287 = 8748400
137 + 8748263 = 8748400
191 + 8748209 = 8748400
197 + 8748203 = 8748400
233 + 8748167 = 8748400
239 + 8748161 = 8748400

Showing the first eight; more decompositions exist.
