Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33553572, here are decompositions:

23 + 33553549 = 33553572
53 + 33553519 = 33553572
61 + 33553511 = 33553572
83 + 33553489 = 33553572
109 + 33553463 = 33553572
193 + 33553379 = 33553572
271 + 33553301 = 33553572
379 + 33553193 = 33553572

Showing the first eight; more decompositions exist.
