Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 526620, here are decompositions:

19 + 526601 = 526620
37 + 526583 = 526620
47 + 526573 = 526620
89 + 526531 = 526620
109 + 526511 = 526620
137 + 526483 = 526620
167 + 526453 = 526620
179 + 526441 = 526620

Showing the first eight; more decompositions exist.
