Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8728532, here are decompositions:

19 + 8728513 = 8728532
61 + 8728471 = 8728532
151 + 8728381 = 8728532
223 + 8728309 = 8728532
229 + 8728303 = 8728532
271 + 8728261 = 8728532
601 + 8727931 = 8728532
619 + 8727913 = 8728532

Showing the first eight; more decompositions exist.
