Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 526138, here are decompositions:

17 + 526121 = 526138
71 + 526067 = 526138
89 + 526049 = 526138
101 + 526037 = 526138
191 + 525947 = 526138
251 + 525887 = 526138
269 + 525869 = 526138
419 + 525719 = 526138

Showing the first eight; more decompositions exist.
