Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 525166, here are decompositions:

3 + 525163 = 525166
23 + 525143 = 525166
29 + 525137 = 525166
137 + 525029 = 525166
149 + 525017 = 525166
167 + 524999 = 525166
197 + 524969 = 525166
227 + 524939 = 525166

Showing the first eight; more decompositions exist.
