Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 528636, here are decompositions:

5 + 528631 = 528636
7 + 528629 = 528636
13 + 528623 = 528636
109 + 528527 = 528636
127 + 528509 = 528636
149 + 528487 = 528636
167 + 528469 = 528636
223 + 528413 = 528636

Showing the first eight; more decompositions exist.
