Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8681352, here are decompositions:

11 + 8681341 = 8681352
41 + 8681311 = 8681352
61 + 8681291 = 8681352
89 + 8681263 = 8681352
101 + 8681251 = 8681352
109 + 8681243 = 8681352
131 + 8681221 = 8681352
139 + 8681213 = 8681352

Showing the first eight; more decompositions exist.
