Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 526556, here are decompositions:

13 + 526543 = 526556
73 + 526483 = 526556
97 + 526459 = 526556
103 + 526453 = 526556
127 + 526429 = 526556
307 + 526249 = 526556
367 + 526189 = 526556
397 + 526159 = 526556

Showing the first eight; more decompositions exist.
