Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 521450, here are decompositions:

3 + 521447 = 521450
73 + 521377 = 521450
151 + 521299 = 521450
199 + 521251 = 521450
271 + 521179 = 521450
277 + 521173 = 521450
283 + 521167 = 521450
313 + 521137 = 521450

Showing the first eight; more decompositions exist.
