Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33545872, here are decompositions:

53 + 33545819 = 33545872
83 + 33545789 = 33545872
89 + 33545783 = 33545872
149 + 33545723 = 33545872
179 + 33545693 = 33545872
263 + 33545609 = 33545872
281 + 33545591 = 33545872
293 + 33545579 = 33545872

Showing the first eight; more decompositions exist.
