Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 525170, here are decompositions:

3 + 525167 = 525170
7 + 525163 = 525170
13 + 525157 = 525170
43 + 525127 = 525170
127 + 525043 = 525170
157 + 525013 = 525170
199 + 524971 = 525170
211 + 524959 = 525170

Showing the first eight; more decompositions exist.
