Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8681744, here are decompositions:

7 + 8681737 = 8681744
13 + 8681731 = 8681744
37 + 8681707 = 8681744
157 + 8681587 = 8681744
241 + 8681503 = 8681744
271 + 8681473 = 8681744
277 + 8681467 = 8681744
367 + 8681377 = 8681744

Showing the first eight; more decompositions exist.
