Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 528732, here are decompositions:

13 + 528719 = 528732
23 + 528709 = 528732
41 + 528691 = 528732
53 + 528679 = 528732
59 + 528673 = 528732
73 + 528659 = 528732
101 + 528631 = 528732
103 + 528629 = 528732

Showing the first eight; more decompositions exist.
