Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 526404, here are decompositions:

7 + 526397 = 526404
13 + 526391 = 526404
17 + 526387 = 526404
23 + 526381 = 526404
31 + 526373 = 526404
37 + 526367 = 526404
97 + 526307 = 526404
107 + 526297 = 526404

Showing the first eight; more decompositions exist.
