Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 526458, here are decompositions:

5 + 526453 = 526458
17 + 526441 = 526458
29 + 526429 = 526458
61 + 526397 = 526458
67 + 526391 = 526458
71 + 526387 = 526458
151 + 526307 = 526458
167 + 526291 = 526458

Showing the first eight; more decompositions exist.
