Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 528620, here are decompositions:

61 + 528559 = 528620
109 + 528511 = 528620
151 + 528469 = 528620
229 + 528391 = 528620
307 + 528313 = 528620
331 + 528289 = 528620
373 + 528247 = 528620
397 + 528223 = 528620

Showing the first eight; more decompositions exist.
