Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 528726, here are decompositions:

7 + 528719 = 528726
17 + 528709 = 528726
19 + 528707 = 528726
47 + 528679 = 528726
53 + 528673 = 528726
59 + 528667 = 528726
67 + 528659 = 528726
97 + 528629 = 528726

Showing the first eight; more decompositions exist.
