Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8681842, here are decompositions:

5 + 8681837 = 8681842
11 + 8681831 = 8681842
53 + 8681789 = 8681842
149 + 8681693 = 8681842
173 + 8681669 = 8681842
179 + 8681663 = 8681842
263 + 8681579 = 8681842
293 + 8681549 = 8681842

Showing the first eight; more decompositions exist.
