Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 521298, here are decompositions:

17 + 521281 = 521298
31 + 521267 = 521298
47 + 521251 = 521298
67 + 521231 = 521298
97 + 521201 = 521298
131 + 521167 = 521298
137 + 521161 = 521298
179 + 521119 = 521298

Showing the first eight; more decompositions exist.
