Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8681402, here are decompositions:

43 + 8681359 = 8681402
61 + 8681341 = 8681402
139 + 8681263 = 8681402
151 + 8681251 = 8681402
181 + 8681221 = 8681402
211 + 8681191 = 8681402
271 + 8681131 = 8681402
313 + 8681089 = 8681402

Showing the first eight; more decompositions exist.
