Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 528684, here are decompositions:

5 + 528679 = 528684
11 + 528673 = 528684
17 + 528667 = 528684
53 + 528631 = 528684
61 + 528623 = 528684
73 + 528611 = 528684
157 + 528527 = 528684
173 + 528511 = 528684

Showing the first eight; more decompositions exist.
