Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 526212, here are decompositions:

13 + 526199 = 526212
19 + 526193 = 526212
23 + 526189 = 526212
53 + 526159 = 526212
73 + 526139 = 526212
139 + 526073 = 526212
149 + 526063 = 526212
163 + 526049 = 526212

Showing the first eight; more decompositions exist.
