Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8681318, here are decompositions:

7 + 8681311 = 8681318
31 + 8681287 = 8681318
67 + 8681251 = 8681318
97 + 8681221 = 8681318
127 + 8681191 = 8681318
229 + 8681089 = 8681318
241 + 8681077 = 8681318
271 + 8681047 = 8681318

Showing the first eight; more decompositions exist.
