Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8681408, here are decompositions:

7 + 8681401 = 8681408
31 + 8681377 = 8681408
67 + 8681341 = 8681408
97 + 8681311 = 8681408
157 + 8681251 = 8681408
277 + 8681131 = 8681408
331 + 8681077 = 8681408
349 + 8681059 = 8681408

Showing the first eight; more decompositions exist.
