Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 526828, here are decompositions:

47 + 526781 = 526828
89 + 526739 = 526828
149 + 526679 = 526828
179 + 526649 = 526828
191 + 526637 = 526828
227 + 526601 = 526828
257 + 526571 = 526828
317 + 526511 = 526828

Showing the first eight; more decompositions exist.
