Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8724524, here are decompositions:

13 + 8724511 = 8724524
31 + 8724493 = 8724524
37 + 8724487 = 8724524
103 + 8724421 = 8724524
223 + 8724301 = 8724524
241 + 8724283 = 8724524
271 + 8724253 = 8724524
283 + 8724241 = 8724524

Showing the first eight; more decompositions exist.
