Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 521052, here are decompositions:

5 + 521047 = 521052
11 + 521041 = 521052
13 + 521039 = 521052
29 + 521023 = 521052
31 + 521021 = 521052
43 + 521009 = 521052
71 + 520981 = 521052
83 + 520969 = 521052

Showing the first eight; more decompositions exist.
