Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33508840, here are decompositions:

11 + 33508829 = 33508840
23 + 33508817 = 33508840
59 + 33508781 = 33508840
107 + 33508733 = 33508840
179 + 33508661 = 33508840
257 + 33508583 = 33508840
263 + 33508577 = 33508840
353 + 33508487 = 33508840

Showing the first eight; more decompositions exist.
