Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33591720, here are decompositions:

17 + 33591703 = 33591720
37 + 33591683 = 33591720
53 + 33591667 = 33591720
61 + 33591659 = 33591720
67 + 33591653 = 33591720
73 + 33591647 = 33591720
79 + 33591641 = 33591720
83 + 33591637 = 33591720

Showing the first eight; more decompositions exist.
