Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 525668, here are decompositions:

19 + 525649 = 525668
61 + 525607 = 525668
97 + 525571 = 525668
127 + 525541 = 525668
139 + 525529 = 525668
151 + 525517 = 525668
211 + 525457 = 525668
229 + 525439 = 525668

Showing the first eight; more decompositions exist.
