Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33872, here are decompositions:

43 + 33829 = 33872
61 + 33811 = 33872
103 + 33769 = 33872
151 + 33721 = 33872
193 + 33679 = 33872
271 + 33601 = 33872
283 + 33589 = 33872
379 + 33493 = 33872

Showing the first eight; more decompositions exist.
