Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8748280, here are decompositions:

3 + 8748277 = 8748280
17 + 8748263 = 8748280
71 + 8748209 = 8748280
89 + 8748191 = 8748280
113 + 8748167 = 8748280
137 + 8748143 = 8748280
263 + 8748017 = 8748280
269 + 8748011 = 8748280

Showing the first eight; more decompositions exist.
