Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33585680, here are decompositions:

43 + 33585637 = 33585680
61 + 33585619 = 33585680
67 + 33585613 = 33585680
97 + 33585583 = 33585680
127 + 33585553 = 33585680
277 + 33585403 = 33585680
439 + 33585241 = 33585680
547 + 33585133 = 33585680

Showing the first eight; more decompositions exist.
