Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33555388, here are decompositions:

5 + 33555383 = 33555388
11 + 33555377 = 33555388
47 + 33555341 = 33555388
71 + 33555317 = 33555388
101 + 33555287 = 33555388
107 + 33555281 = 33555388
137 + 33555251 = 33555388
179 + 33555209 = 33555388

Showing the first eight; more decompositions exist.
