Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 526228, here are decompositions:

5 + 526223 = 526228
29 + 526199 = 526228
71 + 526157 = 526228
89 + 526139 = 526228
107 + 526121 = 526228
179 + 526049 = 526228
191 + 526037 = 526228
281 + 525947 = 526228

Showing the first eight; more decompositions exist.
