Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8728502, here are decompositions:

19 + 8728483 = 8728502
31 + 8728471 = 8728502
193 + 8728309 = 8728502
199 + 8728303 = 8728502
229 + 8728273 = 8728502
241 + 8728261 = 8728502
373 + 8728129 = 8728502
571 + 8727931 = 8728502

Showing the first eight; more decompositions exist.
