Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8728648, here are decompositions:

41 + 8728607 = 8728648
167 + 8728481 = 8728648
191 + 8728457 = 8728648
251 + 8728397 = 8728648
317 + 8728331 = 8728648
359 + 8728289 = 8728648
479 + 8728169 = 8728648
569 + 8728079 = 8728648

Showing the first eight; more decompositions exist.
