Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 526210, here are decompositions:

11 + 526199 = 526210
17 + 526193 = 526210
53 + 526157 = 526210
71 + 526139 = 526210
89 + 526121 = 526210
137 + 526073 = 526210
173 + 526037 = 526210
227 + 525983 = 526210

Showing the first eight; more decompositions exist.
