Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 521958, here are decompositions:

29 + 521929 = 521958
61 + 521897 = 521958
71 + 521887 = 521958
79 + 521879 = 521958
89 + 521869 = 521958
97 + 521861 = 521958
127 + 521831 = 521958
139 + 521819 = 521958

Showing the first eight; more decompositions exist.
