Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8681348, here are decompositions:

7 + 8681341 = 8681348
31 + 8681317 = 8681348
37 + 8681311 = 8681348
61 + 8681287 = 8681348
97 + 8681251 = 8681348
127 + 8681221 = 8681348
157 + 8681191 = 8681348
271 + 8681077 = 8681348

Showing the first eight; more decompositions exist.
