Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 528986, here are decompositions:

13 + 528973 = 528986
19 + 528967 = 528986
103 + 528883 = 528986
109 + 528877 = 528986
163 + 528823 = 528986
223 + 528763 = 528986
277 + 528709 = 528986
307 + 528679 = 528986

Showing the first eight; more decompositions exist.
