Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 525222, here are decompositions:

13 + 525209 = 525222
23 + 525199 = 525222
29 + 525193 = 525222
31 + 525191 = 525222
59 + 525163 = 525222
79 + 525143 = 525222
179 + 525043 = 525222
193 + 525029 = 525222

Showing the first eight; more decompositions exist.
