Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 526728, here are decompositions:

11 + 526717 = 526728
19 + 526709 = 526728
47 + 526681 = 526728
61 + 526667 = 526728
71 + 526657 = 526728
79 + 526649 = 526728
101 + 526627 = 526728
109 + 526619 = 526728

Showing the first eight; more decompositions exist.
