Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 526156, here are decompositions:

17 + 526139 = 526156
83 + 526073 = 526156
89 + 526067 = 526156
107 + 526049 = 526156
173 + 525983 = 526156
233 + 525923 = 526156
263 + 525893 = 526156
269 + 525887 = 526156

Showing the first eight; more decompositions exist.
