Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 521310, here are decompositions:

11 + 521299 = 521310
29 + 521281 = 521310
43 + 521267 = 521310
59 + 521251 = 521310
67 + 521243 = 521310
79 + 521231 = 521310
109 + 521201 = 521310
131 + 521179 = 521310

Showing the first eight; more decompositions exist.
