Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 526540, here are decompositions:

29 + 526511 = 526540
41 + 526499 = 526540
149 + 526391 = 526540
167 + 526373 = 526540
173 + 526367 = 526540
233 + 526307 = 526540
251 + 526289 = 526540
257 + 526283 = 526540

Showing the first eight; more decompositions exist.
