Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 526978, here are decompositions:

41 + 526937 = 526978
47 + 526931 = 526978
107 + 526871 = 526978
149 + 526829 = 526978
197 + 526781 = 526978
239 + 526739 = 526978
269 + 526709 = 526978
311 + 526667 = 526978

Showing the first eight; more decompositions exist.
