Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 526144, here are decompositions:

5 + 526139 = 526144
23 + 526121 = 526144
71 + 526073 = 526144
107 + 526037 = 526144
191 + 525953 = 526144
197 + 525947 = 526144
251 + 525893 = 526144
257 + 525887 = 526144

Showing the first eight; more decompositions exist.
