Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8620572, here are decompositions:

5 + 8620567 = 8620572
19 + 8620553 = 8620572
29 + 8620543 = 8620572
43 + 8620529 = 8620572
73 + 8620499 = 8620572
179 + 8620393 = 8620572
211 + 8620361 = 8620572
223 + 8620349 = 8620572

Showing the first eight; more decompositions exist.
