Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33493872, here are decompositions:

31 + 33493841 = 33493872
43 + 33493829 = 33493872
59 + 33493813 = 33493872
89 + 33493783 = 33493872
179 + 33493693 = 33493872
199 + 33493673 = 33493872
233 + 33493639 = 33493872
271 + 33493601 = 33493872

Showing the first eight; more decompositions exist.
