Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 521776, here are decompositions:

23 + 521753 = 521776
53 + 521723 = 521776
83 + 521693 = 521776
107 + 521669 = 521776
173 + 521603 = 521776
239 + 521537 = 521776
257 + 521519 = 521776
293 + 521483 = 521776

Showing the first eight; more decompositions exist.
