Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 526644, here are decompositions:

7 + 526637 = 526644
11 + 526633 = 526644
17 + 526627 = 526644
43 + 526601 = 526644
61 + 526583 = 526644
71 + 526573 = 526644
73 + 526571 = 526644
101 + 526543 = 526644

Showing the first eight; more decompositions exist.
