Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 521364, here are decompositions:

5 + 521359 = 521364
7 + 521357 = 521364
47 + 521317 = 521364
83 + 521281 = 521364
97 + 521267 = 521364
113 + 521251 = 521364
163 + 521201 = 521364
191 + 521173 = 521364

Showing the first eight; more decompositions exist.
