Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 521358, here are decompositions:

29 + 521329 = 521358
41 + 521317 = 521358
59 + 521299 = 521358
107 + 521251 = 521358
127 + 521231 = 521358
157 + 521201 = 521358
179 + 521179 = 521358
181 + 521177 = 521358

Showing the first eight; more decompositions exist.
