Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8681342, here are decompositions:

31 + 8681311 = 8681342
79 + 8681263 = 8681342
151 + 8681191 = 8681342
211 + 8681131 = 8681342
283 + 8681059 = 8681342
349 + 8680993 = 8681342
421 + 8680921 = 8681342
433 + 8680909 = 8681342

Showing the first eight; more decompositions exist.
