Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8681344, here are decompositions:

3 + 8681341 = 8681344
53 + 8681291 = 8681344
101 + 8681243 = 8681344
131 + 8681213 = 8681344
137 + 8681207 = 8681344
167 + 8681177 = 8681344
227 + 8681117 = 8681344
233 + 8681111 = 8681344

Showing the first eight; more decompositions exist.
