Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33553072, here are decompositions:

23 + 33553049 = 33553072
71 + 33553001 = 33553072
89 + 33552983 = 33553072
149 + 33552923 = 33553072
263 + 33552809 = 33553072
401 + 33552671 = 33553072
431 + 33552641 = 33553072
653 + 33552419 = 33553072

Showing the first eight; more decompositions exist.
