Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33545388, here are decompositions:

5 + 33545383 = 33545388
7 + 33545381 = 33545388
11 + 33545377 = 33545388
17 + 33545371 = 33545388
59 + 33545329 = 33545388
61 + 33545327 = 33545388
67 + 33545321 = 33545388
137 + 33545251 = 33545388

Showing the first eight; more decompositions exist.
