Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 528658, here are decompositions:

29 + 528629 = 528658
47 + 528611 = 528658
131 + 528527 = 528658
149 + 528509 = 528658
167 + 528491 = 528658
239 + 528419 = 528658
257 + 528401 = 528658
359 + 528299 = 528658

Showing the first eight; more decompositions exist.
