Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 526158, here are decompositions:

19 + 526139 = 526158
37 + 526121 = 526158
41 + 526117 = 526158
71 + 526087 = 526158
89 + 526069 = 526158
107 + 526051 = 526158
109 + 526049 = 526158
131 + 526027 = 526158

Showing the first eight; more decompositions exist.
