Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8681726, here are decompositions:

19 + 8681707 = 8681726
103 + 8681623 = 8681726
139 + 8681587 = 8681726
223 + 8681503 = 8681726
349 + 8681377 = 8681726
367 + 8681359 = 8681726
409 + 8681317 = 8681726
439 + 8681287 = 8681726

Showing the first eight; more decompositions exist.
