Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33555872, here are decompositions:

13 + 33555859 = 33555872
19 + 33555853 = 33555872
73 + 33555799 = 33555872
193 + 33555679 = 33555872
211 + 33555661 = 33555872
373 + 33555499 = 33555872
379 + 33555493 = 33555872
433 + 33555439 = 33555872

Showing the first eight; more decompositions exist.
