Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 528590, here are decompositions:

31 + 528559 = 528590
79 + 528511 = 528590
103 + 528487 = 528590
157 + 528433 = 528590
199 + 528391 = 528590
277 + 528313 = 528590
367 + 528223 = 528590
373 + 528217 = 528590

Showing the first eight; more decompositions exist.
