Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 521262, here are decompositions:

11 + 521251 = 521262
19 + 521243 = 521262
31 + 521231 = 521262
61 + 521201 = 521262
83 + 521179 = 521262
89 + 521173 = 521262
101 + 521161 = 521262
109 + 521153 = 521262

Showing the first eight; more decompositions exist.
