Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33608380, here are decompositions:

11 + 33608369 = 33608380
17 + 33608363 = 33608380
107 + 33608273 = 33608380
167 + 33608213 = 33608380
263 + 33608117 = 33608380
347 + 33608033 = 33608380
353 + 33608027 = 33608380
431 + 33607949 = 33608380

Showing the first eight; more decompositions exist.
