Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 526428, here are decompositions:

5 + 526423 = 526428
31 + 526397 = 526428
37 + 526391 = 526428
41 + 526387 = 526428
47 + 526381 = 526428
61 + 526367 = 526428
131 + 526297 = 526428
137 + 526291 = 526428

Showing the first eight; more decompositions exist.
