Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8749648, here are decompositions:

41 + 8749607 = 8749648
59 + 8749589 = 8749648
179 + 8749469 = 8749648
191 + 8749457 = 8749648
197 + 8749451 = 8749648
227 + 8749421 = 8749648
311 + 8749337 = 8749648
317 + 8749331 = 8749648

Showing the first eight; more decompositions exist.
