Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33553220, here are decompositions:

67 + 33553153 = 33553220
79 + 33553141 = 33553220
163 + 33553057 = 33553220
193 + 33553027 = 33553220
271 + 33552949 = 33553220
367 + 33552853 = 33553220
397 + 33552823 = 33553220
409 + 33552811 = 33553220

Showing the first eight; more decompositions exist.
