Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 525180, here are decompositions:

13 + 525167 = 525180
17 + 525163 = 525180
23 + 525157 = 525180
37 + 525143 = 525180
43 + 525137 = 525180
53 + 525127 = 525180
79 + 525101 = 525180
137 + 525043 = 525180

Showing the first eight; more decompositions exist.
