Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 525172, here are decompositions:

5 + 525167 = 525172
29 + 525143 = 525172
71 + 525101 = 525172
173 + 524999 = 525172
191 + 524981 = 525172
233 + 524939 = 525172
239 + 524933 = 525172
251 + 524921 = 525172

Showing the first eight; more decompositions exist.
