Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8748406, here are decompositions:

3 + 8748403 = 8748406
47 + 8748359 = 8748406
83 + 8748323 = 8748406
197 + 8748209 = 8748406
239 + 8748167 = 8748406
263 + 8748143 = 8748406
269 + 8748137 = 8748406
389 + 8748017 = 8748406

Showing the first eight; more decompositions exist.
