Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 521458, here are decompositions:

11 + 521447 = 521458
29 + 521429 = 521458
59 + 521399 = 521458
89 + 521369 = 521458
101 + 521357 = 521458
149 + 521309 = 521458
191 + 521267 = 521458
227 + 521231 = 521458

Showing the first eight; more decompositions exist.
