Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8681464, here are decompositions:

17 + 8681447 = 8681464
101 + 8681363 = 8681464
107 + 8681357 = 8681464
173 + 8681291 = 8681464
251 + 8681213 = 8681464
257 + 8681207 = 8681464
347 + 8681117 = 8681464
353 + 8681111 = 8681464

Showing the first eight; more decompositions exist.
