Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 521446, here are decompositions:

17 + 521429 = 521446
47 + 521399 = 521446
53 + 521393 = 521446
83 + 521363 = 521446
89 + 521357 = 521446
137 + 521309 = 521446
179 + 521267 = 521446
269 + 521177 = 521446

Showing the first eight; more decompositions exist.
