Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 528572, here are decompositions:

13 + 528559 = 528572
61 + 528511 = 528572
103 + 528469 = 528572
139 + 528433 = 528572
181 + 528391 = 528572
199 + 528373 = 528572
283 + 528289 = 528572
349 + 528223 = 528572

Showing the first eight; more decompositions exist.
