Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 526288, here are decompositions:

5 + 526283 = 526288
17 + 526271 = 526288
89 + 526199 = 526288
131 + 526157 = 526288
149 + 526139 = 526288
167 + 526121 = 526288
239 + 526049 = 526288
251 + 526037 = 526288

Showing the first eight; more decompositions exist.
