Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 528978, here are decompositions:

5 + 528973 = 528978
7 + 528971 = 528978
11 + 528967 = 528978
31 + 528947 = 528978
67 + 528911 = 528978
97 + 528881 = 528978
101 + 528877 = 528978
157 + 528821 = 528978

Showing the first eight; more decompositions exist.
