Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 528700, here are decompositions:

41 + 528659 = 528700
71 + 528629 = 528700
89 + 528611 = 528700
173 + 528527 = 528700
191 + 528509 = 528700
281 + 528419 = 528700
317 + 528383 = 528700
383 + 528317 = 528700

Showing the first eight; more decompositions exist.
