Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8681696, here are decompositions:

3 + 8681693 = 8681696
73 + 8681623 = 8681696
109 + 8681587 = 8681696
157 + 8681539 = 8681696
193 + 8681503 = 8681696
223 + 8681473 = 8681696
229 + 8681467 = 8681696
337 + 8681359 = 8681696

Showing the first eight; more decompositions exist.
