Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8681498, here are decompositions:

31 + 8681467 = 8681498
97 + 8681401 = 8681498
139 + 8681359 = 8681498
157 + 8681341 = 8681498
181 + 8681317 = 8681498
211 + 8681287 = 8681498
277 + 8681221 = 8681498
307 + 8681191 = 8681498

Showing the first eight; more decompositions exist.
