Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33608780, here are decompositions:

43 + 33608737 = 33608780
61 + 33608719 = 33608780
97 + 33608683 = 33608780
151 + 33608629 = 33608780
199 + 33608581 = 33608780
211 + 33608569 = 33608780
241 + 33608539 = 33608780
313 + 33608467 = 33608780

Showing the first eight; more decompositions exist.
