Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 521454, here are decompositions:

7 + 521447 = 521454
53 + 521401 = 521454
61 + 521393 = 521454
97 + 521357 = 521454
137 + 521317 = 521454
173 + 521281 = 521454
211 + 521243 = 521454
223 + 521231 = 521454

Showing the first eight; more decompositions exist.
