Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8681350, here are decompositions:

59 + 8681291 = 8681350
107 + 8681243 = 8681350
137 + 8681213 = 8681350
173 + 8681177 = 8681350
191 + 8681159 = 8681350
233 + 8681117 = 8681350
239 + 8681111 = 8681350
347 + 8681003 = 8681350

Showing the first eight; more decompositions exist.
