Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 525366, here are decompositions:

5 + 525361 = 525366
7 + 525359 = 525366
13 + 525353 = 525366
53 + 525313 = 525366
67 + 525299 = 525366
109 + 525257 = 525366
113 + 525253 = 525366
157 + 525209 = 525366

Showing the first eight; more decompositions exist.
