Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 528788, here are decompositions:

79 + 528709 = 528788
97 + 528691 = 528788
109 + 528679 = 528788
157 + 528631 = 528788
229 + 528559 = 528788
277 + 528511 = 528788
397 + 528391 = 528788
499 + 528289 = 528788

Showing the first eight; more decompositions exist.
