Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 528012, here are decompositions:

11 + 528001 = 528012
19 + 527993 = 528012
29 + 527983 = 528012
31 + 527981 = 528012
71 + 527941 = 528012
83 + 527929 = 528012
103 + 527909 = 528012
131 + 527881 = 528012

Showing the first eight; more decompositions exist.
