Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8681330, here are decompositions:

13 + 8681317 = 8681330
19 + 8681311 = 8681330
43 + 8681287 = 8681330
67 + 8681263 = 8681330
79 + 8681251 = 8681330
109 + 8681221 = 8681330
139 + 8681191 = 8681330
199 + 8681131 = 8681330

Showing the first eight; more decompositions exist.
