Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 526388, here are decompositions:

7 + 526381 = 526388
97 + 526291 = 526388
139 + 526249 = 526388
157 + 526231 = 526388
199 + 526189 = 526388
229 + 526159 = 526388
271 + 526117 = 526388
337 + 526051 = 526388

Showing the first eight; more decompositions exist.
