Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 525370, here are decompositions:

11 + 525359 = 525370
17 + 525353 = 525370
71 + 525299 = 525370
113 + 525257 = 525370
149 + 525221 = 525370
179 + 525191 = 525370
227 + 525143 = 525370
233 + 525137 = 525370

Showing the first eight; more decompositions exist.
