Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8681728, here are decompositions:

59 + 8681669 = 8681728
89 + 8681639 = 8681728
149 + 8681579 = 8681728
179 + 8681549 = 8681728
239 + 8681489 = 8681728
281 + 8681447 = 8681728
359 + 8681369 = 8681728
521 + 8681207 = 8681728

Showing the first eight; more decompositions exist.
