Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 525620, here are decompositions:

13 + 525607 = 525620
37 + 525583 = 525620
79 + 525541 = 525620
103 + 525517 = 525620
127 + 525493 = 525620
163 + 525457 = 525620
181 + 525439 = 525620
211 + 525409 = 525620

Showing the first eight; more decompositions exist.
