Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33556540, here are decompositions:

11 + 33556529 = 33556540
41 + 33556499 = 33556540
47 + 33556493 = 33556540
137 + 33556403 = 33556540
179 + 33556361 = 33556540
197 + 33556343 = 33556540
239 + 33556301 = 33556540
383 + 33556157 = 33556540

Showing the first eight; more decompositions exist.
