Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 521746, here are decompositions:

3 + 521743 = 521746
23 + 521723 = 521746
53 + 521693 = 521746
89 + 521657 = 521746
179 + 521567 = 521746
227 + 521519 = 521746
263 + 521483 = 521746
317 + 521429 = 521746

Showing the first eight; more decompositions exist.
