Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8728636, here are decompositions:

29 + 8728607 = 8728636
179 + 8728457 = 8728636
239 + 8728397 = 8728636
263 + 8728373 = 8728636
347 + 8728289 = 8728636
443 + 8728193 = 8728636
467 + 8728169 = 8728636
557 + 8728079 = 8728636

Showing the first eight; more decompositions exist.
