Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 521574, here are decompositions:

7 + 521567 = 521574
17 + 521557 = 521574
23 + 521551 = 521574
37 + 521537 = 521574
41 + 521533 = 521574
47 + 521527 = 521574
71 + 521503 = 521574
83 + 521491 = 521574

Showing the first eight; more decompositions exist.
