Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 528678, here are decompositions:

5 + 528673 = 528678
11 + 528667 = 528678
19 + 528659 = 528678
47 + 528631 = 528678
67 + 528611 = 528678
151 + 528527 = 528678
167 + 528511 = 528678
191 + 528487 = 528678

Showing the first eight; more decompositions exist.
