Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8681364, here are decompositions:

5 + 8681359 = 8681364
7 + 8681357 = 8681364
23 + 8681341 = 8681364
47 + 8681317 = 8681364
53 + 8681311 = 8681364
73 + 8681291 = 8681364
101 + 8681263 = 8681364
113 + 8681251 = 8681364

Showing the first eight; more decompositions exist.
