Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 528942, here are decompositions:

13 + 528929 = 528942
31 + 528911 = 528942
59 + 528883 = 528942
61 + 528881 = 528942
79 + 528863 = 528942
109 + 528833 = 528942
131 + 528811 = 528942
151 + 528791 = 528942

Showing the first eight; more decompositions exist.
