Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 525200, here are decompositions:

7 + 525193 = 525200
37 + 525163 = 525200
43 + 525157 = 525200
73 + 525127 = 525200
157 + 525043 = 525200
199 + 525001 = 525200
229 + 524971 = 525200
241 + 524959 = 525200

Showing the first eight; more decompositions exist.
