Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8681698, here are decompositions:

5 + 8681693 = 8681698
29 + 8681669 = 8681698
59 + 8681639 = 8681698
131 + 8681567 = 8681698
149 + 8681549 = 8681698
191 + 8681507 = 8681698
251 + 8681447 = 8681698
269 + 8681429 = 8681698

Showing the first eight; more decompositions exist.
