Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8681436, here are decompositions:

7 + 8681429 = 8681436
59 + 8681377 = 8681436
67 + 8681369 = 8681436
73 + 8681363 = 8681436
79 + 8681357 = 8681436
149 + 8681287 = 8681436
173 + 8681263 = 8681436
193 + 8681243 = 8681436

Showing the first eight; more decompositions exist.
