Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 526858, here are decompositions:

5 + 526853 = 526858
29 + 526829 = 526858
149 + 526709 = 526858
179 + 526679 = 526858
191 + 526667 = 526858
239 + 526619 = 526858
257 + 526601 = 526858
347 + 526511 = 526858

Showing the first eight; more decompositions exist.
