Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 521482, here are decompositions:

11 + 521471 = 521482
53 + 521429 = 521482
83 + 521399 = 521482
89 + 521393 = 521482
113 + 521369 = 521482
173 + 521309 = 521482
239 + 521243 = 521482
251 + 521231 = 521482

Showing the first eight; more decompositions exist.
