Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33530790, here are decompositions:

17 + 33530773 = 33530790
31 + 33530759 = 33530790
61 + 33530729 = 33530790
89 + 33530701 = 33530790
113 + 33530677 = 33530790
173 + 33530617 = 33530790
193 + 33530597 = 33530790
197 + 33530593 = 33530790

Showing the first eight; more decompositions exist.
