Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33553280, here are decompositions:

109 + 33553171 = 33553280
127 + 33553153 = 33553280
139 + 33553141 = 33553280
223 + 33553057 = 33553280
331 + 33552949 = 33553280
421 + 33552859 = 33553280
457 + 33552823 = 33553280
571 + 33552709 = 33553280

Showing the first eight; more decompositions exist.
