Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33489872, here are decompositions:

43 + 33489829 = 33489872
103 + 33489769 = 33489872
109 + 33489763 = 33489872
223 + 33489649 = 33489872
313 + 33489559 = 33489872
439 + 33489433 = 33489872
523 + 33489349 = 33489872
631 + 33489241 = 33489872

Showing the first eight; more decompositions exist.
