Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 528488, here are decompositions:

19 + 528469 = 528488
97 + 528391 = 528488
199 + 528289 = 528488
241 + 528247 = 528488
271 + 528217 = 528488
397 + 528091 = 528488
487 + 528001 = 528488
547 + 527941 = 528488

Showing the first eight; more decompositions exist.
