Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8727528, here are decompositions:

31 + 8727497 = 8727528
97 + 8727431 = 8727528
101 + 8727427 = 8727528
179 + 8727349 = 8727528
211 + 8727317 = 8727528
241 + 8727287 = 8727528
281 + 8727247 = 8727528
317 + 8727211 = 8727528

Showing the first eight; more decompositions exist.
