Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33489728, here are decompositions:

79 + 33489649 = 33489728
109 + 33489619 = 33489728
367 + 33489361 = 33489728
379 + 33489349 = 33489728
409 + 33489319 = 33489728
487 + 33489241 = 33489728
577 + 33489151 = 33489728
619 + 33489109 = 33489728

Showing the first eight; more decompositions exist.
