Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8681836, here are decompositions:

5 + 8681831 = 8681836
47 + 8681789 = 8681836
167 + 8681669 = 8681836
173 + 8681663 = 8681836
197 + 8681639 = 8681836
257 + 8681579 = 8681836
269 + 8681567 = 8681836
347 + 8681489 = 8681836

Showing the first eight; more decompositions exist.
