Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 526266, here are decompositions:

17 + 526249 = 526266
43 + 526223 = 526266
53 + 526213 = 526266
67 + 526199 = 526266
73 + 526193 = 526266
107 + 526159 = 526266
109 + 526157 = 526266
127 + 526139 = 526266

Showing the first eight; more decompositions exist.
