Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 525186, here are decompositions:

19 + 525167 = 525186
23 + 525163 = 525186
29 + 525157 = 525186
43 + 525143 = 525186
59 + 525127 = 525186
157 + 525029 = 525186
173 + 525013 = 525186
223 + 524963 = 525186

Showing the first eight; more decompositions exist.
