Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8681252, here are decompositions:

31 + 8681221 = 8681252
61 + 8681191 = 8681252
163 + 8681089 = 8681252
193 + 8681059 = 8681252
313 + 8680939 = 8681252
331 + 8680921 = 8681252
439 + 8680813 = 8681252
499 + 8680753 = 8681252

Showing the first eight; more decompositions exist.
