Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8748628, here are decompositions:

29 + 8748599 = 8748628
41 + 8748587 = 8748628
47 + 8748581 = 8748628
197 + 8748431 = 8748628
269 + 8748359 = 8748628
347 + 8748281 = 8748628
419 + 8748209 = 8748628
461 + 8748167 = 8748628

Showing the first eight; more decompositions exist.
