Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33553208, here are decompositions:

37 + 33553171 = 33553208
67 + 33553141 = 33553208
151 + 33553057 = 33553208
181 + 33553027 = 33553208
349 + 33552859 = 33553208
379 + 33552829 = 33553208
397 + 33552811 = 33553208
421 + 33552787 = 33553208

Showing the first eight; more decompositions exist.
