Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 521268, here are decompositions:

17 + 521251 = 521268
37 + 521231 = 521268
67 + 521201 = 521268
89 + 521179 = 521268
101 + 521167 = 521268
107 + 521161 = 521268
131 + 521137 = 521268
149 + 521119 = 521268

Showing the first eight; more decompositions exist.
