Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 521410, here are decompositions:

11 + 521399 = 521410
17 + 521393 = 521410
41 + 521369 = 521410
47 + 521363 = 521410
53 + 521357 = 521410
101 + 521309 = 521410
167 + 521243 = 521410
179 + 521231 = 521410

Showing the first eight; more decompositions exist.
