Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33553172, here are decompositions:

19 + 33553153 = 33553172
31 + 33553141 = 33553172
223 + 33552949 = 33553172
313 + 33552859 = 33553172
349 + 33552823 = 33553172
463 + 33552709 = 33553172
571 + 33552601 = 33553172
643 + 33552529 = 33553172

Showing the first eight; more decompositions exist.
