Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 526866, here are decompositions:

7 + 526859 = 526866
13 + 526853 = 526866
29 + 526837 = 526866
37 + 526829 = 526866
89 + 526777 = 526866
103 + 526763 = 526866
107 + 526759 = 526866
127 + 526739 = 526866

Showing the first eight; more decompositions exist.
