Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 521292, here are decompositions:

11 + 521281 = 521292
41 + 521251 = 521292
61 + 521231 = 521292
113 + 521179 = 521292
131 + 521161 = 521292
139 + 521153 = 521292
173 + 521119 = 521292
229 + 521063 = 521292

Showing the first eight; more decompositions exist.
