Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 526140, here are decompositions:

19 + 526121 = 526140
23 + 526117 = 526140
53 + 526087 = 526140
67 + 526073 = 526140
71 + 526069 = 526140
73 + 526067 = 526140
89 + 526051 = 526140
103 + 526037 = 526140

Showing the first eight; more decompositions exist.
