Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 572656, here are decompositions:

3 + 572653 = 572656
5 + 572651 = 572656
17 + 572639 = 572656
23 + 572633 = 572656
47 + 572609 = 572656
59 + 572597 = 572656
83 + 572573 = 572656
89 + 572567 = 572656

Showing the first eight; more decompositions exist.
