Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33531872, here are decompositions:

19 + 33531853 = 33531872
79 + 33531793 = 33531872
193 + 33531679 = 33531872
211 + 33531661 = 33531872
313 + 33531559 = 33531872
331 + 33531541 = 33531872
373 + 33531499 = 33531872
421 + 33531451 = 33531872

Showing the first eight; more decompositions exist.
