Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 525510, here are decompositions:

17 + 525493 = 525510
19 + 525491 = 525510
43 + 525467 = 525510
53 + 525457 = 525510
71 + 525439 = 525510
79 + 525431 = 525510
101 + 525409 = 525510
113 + 525397 = 525510

Showing the first eight; more decompositions exist.
