Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 525028, here are decompositions:

11 + 525017 = 525028
29 + 524999 = 525028
47 + 524981 = 525028
59 + 524969 = 525028
71 + 524957 = 525028
89 + 524939 = 525028
107 + 524921 = 525028
197 + 524831 = 525028

Showing the first eight; more decompositions exist.
