Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 528524, here are decompositions:

13 + 528511 = 528524
37 + 528487 = 528524
151 + 528373 = 528524
211 + 528313 = 528524
277 + 528247 = 528524
307 + 528217 = 528524
397 + 528127 = 528524
433 + 528091 = 528524

Showing the first eight; more decompositions exist.
