Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 526340, here are decompositions:

43 + 526297 = 526340
109 + 526231 = 526340
127 + 526213 = 526340
151 + 526189 = 526340
181 + 526159 = 526340
223 + 526117 = 526340
271 + 526069 = 526340
277 + 526063 = 526340

Showing the first eight; more decompositions exist.
