Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 526218, here are decompositions:

5 + 526213 = 526218
19 + 526199 = 526218
29 + 526189 = 526218
59 + 526159 = 526218
61 + 526157 = 526218
79 + 526139 = 526218
97 + 526121 = 526218
101 + 526117 = 526218

Showing the first eight; more decompositions exist.
