Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8681326, here are decompositions:

83 + 8681243 = 8681326
113 + 8681213 = 8681326
149 + 8681177 = 8681326
167 + 8681159 = 8681326
197 + 8681129 = 8681326
317 + 8681009 = 8681326
419 + 8680907 = 8681326
503 + 8680823 = 8681326

Showing the first eight; more decompositions exist.
