Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33557412, here are decompositions:

13 + 33557399 = 33557412
71 + 33557341 = 33557412
73 + 33557339 = 33557412
89 + 33557323 = 33557412
269 + 33557143 = 33557412
281 + 33557131 = 33557412
293 + 33557119 = 33557412
311 + 33557101 = 33557412

Showing the first eight; more decompositions exist.
