Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 528026, here are decompositions:

13 + 528013 = 528026
43 + 527983 = 528026
97 + 527929 = 528026
157 + 527869 = 528026
223 + 527803 = 528026
277 + 527749 = 528026
463 + 527563 = 528026
607 + 527419 = 528026

Showing the first eight; more decompositions exist.
