Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33557572, here are decompositions:

5 + 33557567 = 33557572
11 + 33557561 = 33557572
29 + 33557543 = 33557572
101 + 33557471 = 33557572
149 + 33557423 = 33557572
173 + 33557399 = 33557572
233 + 33557339 = 33557572
509 + 33557063 = 33557572

Showing the first eight; more decompositions exist.
