Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 525636, here are decompositions:

29 + 525607 = 525636
37 + 525599 = 525636
43 + 525593 = 525636
53 + 525583 = 525636
103 + 525533 = 525636
107 + 525529 = 525636
179 + 525457 = 525636
197 + 525439 = 525636

Showing the first eight; more decompositions exist.
