Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8646572, here are decompositions:

13 + 8646559 = 8646572
43 + 8646529 = 8646572
61 + 8646511 = 8646572
211 + 8646361 = 8646572
313 + 8646259 = 8646572
349 + 8646223 = 8646572
409 + 8646163 = 8646572
601 + 8645971 = 8646572

Showing the first eight; more decompositions exist.
