Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8681204, here are decompositions:

13 + 8681191 = 8681204
73 + 8681131 = 8681204
127 + 8681077 = 8681204
157 + 8681047 = 8681204
211 + 8680993 = 8681204
283 + 8680921 = 8681204
463 + 8680741 = 8681204
487 + 8680717 = 8681204

Showing the first eight; more decompositions exist.
