Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8681394, here are decompositions:

17 + 8681377 = 8681394
31 + 8681363 = 8681394
37 + 8681357 = 8681394
53 + 8681341 = 8681394
83 + 8681311 = 8681394
103 + 8681291 = 8681394
107 + 8681287 = 8681394
131 + 8681263 = 8681394

Showing the first eight; more decompositions exist.
