Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 521546, here are decompositions:

7 + 521539 = 521546
13 + 521533 = 521546
19 + 521527 = 521546
43 + 521503 = 521546
229 + 521317 = 521546
367 + 521179 = 521546
373 + 521173 = 521546
379 + 521167 = 521546

Showing the first eight; more decompositions exist.
