Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 521548, here are decompositions:

11 + 521537 = 521548
29 + 521519 = 521548
101 + 521447 = 521548
149 + 521399 = 521548
179 + 521369 = 521548
191 + 521357 = 521548
239 + 521309 = 521548
281 + 521267 = 521548

Showing the first eight; more decompositions exist.
