Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 521716, here are decompositions:

23 + 521693 = 521716
47 + 521669 = 521716
59 + 521657 = 521716
113 + 521603 = 521716
149 + 521567 = 521716
179 + 521537 = 521716
197 + 521519 = 521716
233 + 521483 = 521716

Showing the first eight; more decompositions exist.
