Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33555378, here are decompositions:

5 + 33555373 = 33555378
37 + 33555341 = 33555378
61 + 33555317 = 33555378
89 + 33555289 = 33555378
97 + 33555281 = 33555378
107 + 33555271 = 33555378
127 + 33555251 = 33555378
137 + 33555241 = 33555378

Showing the first eight; more decompositions exist.
