Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 526986, here are decompositions:

23 + 526963 = 526986
29 + 526957 = 526986
43 + 526943 = 526986
73 + 526913 = 526986
127 + 526859 = 526986
149 + 526837 = 526986
157 + 526829 = 526986
223 + 526763 = 526986

Showing the first eight; more decompositions exist.
