Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33557472, here are decompositions:

5 + 33557467 = 33557472
19 + 33557453 = 33557472
43 + 33557429 = 33557472
59 + 33557413 = 33557472
61 + 33557411 = 33557472
73 + 33557399 = 33557472
131 + 33557341 = 33557472
149 + 33557323 = 33557472

Showing the first eight; more decompositions exist.
