Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 526180, here are decompositions:

23 + 526157 = 526180
41 + 526139 = 526180
59 + 526121 = 526180
107 + 526073 = 526180
113 + 526067 = 526180
131 + 526049 = 526180
197 + 525983 = 526180
227 + 525953 = 526180

Showing the first eight; more decompositions exist.
