Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 526402, here are decompositions:

5 + 526397 = 526402
11 + 526391 = 526402
29 + 526373 = 526402
113 + 526289 = 526402
131 + 526271 = 526402
179 + 526223 = 526402
263 + 526139 = 526402
281 + 526121 = 526402

Showing the first eight; more decompositions exist.
