Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 525638, here are decompositions:

31 + 525607 = 525638
67 + 525571 = 525638
97 + 525541 = 525638
109 + 525529 = 525638
181 + 525457 = 525638
199 + 525439 = 525638
229 + 525409 = 525638
241 + 525397 = 525638

Showing the first eight; more decompositions exist.
