Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 521896, here are decompositions:

17 + 521879 = 521896
83 + 521813 = 521896
107 + 521789 = 521896
173 + 521723 = 521896
227 + 521669 = 521896
239 + 521657 = 521896
293 + 521603 = 521896
359 + 521537 = 521896

Showing the first eight; more decompositions exist.
