Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33572730, here are decompositions:

17 + 33572713 = 33572730
29 + 33572701 = 33572730
31 + 33572699 = 33572730
43 + 33572687 = 33572730
47 + 33572683 = 33572730
83 + 33572647 = 33572730
101 + 33572629 = 33572730
173 + 33572557 = 33572730

Showing the first eight; more decompositions exist.
