Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33557372, here are decompositions:

31 + 33557341 = 33557372
229 + 33557143 = 33557372
241 + 33557131 = 33557372
271 + 33557101 = 33557372
379 + 33556993 = 33557372
661 + 33556711 = 33557372
691 + 33556681 = 33557372
991 + 33556381 = 33557372

Showing the first eight; more decompositions exist.
