Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33489680, here are decompositions:

31 + 33489649 = 33489680
61 + 33489619 = 33489680
67 + 33489613 = 33489680
97 + 33489583 = 33489680
331 + 33489349 = 33489680
397 + 33489283 = 33489680
439 + 33489241 = 33489680
457 + 33489223 = 33489680

Showing the first eight; more decompositions exist.
