Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8728476, here are decompositions:

5 + 8728471 = 8728476
19 + 8728457 = 8728476
79 + 8728397 = 8728476
89 + 8728387 = 8728476
103 + 8728373 = 8728476
167 + 8728309 = 8728476
173 + 8728303 = 8728476
269 + 8728207 = 8728476

Showing the first eight; more decompositions exist.
