Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33605028, here are decompositions:

11 + 33605017 = 33605028
59 + 33604969 = 33605028
139 + 33604889 = 33605028
151 + 33604877 = 33605028
271 + 33604757 = 33605028
337 + 33604691 = 33605028
419 + 33604609 = 33605028
421 + 33604607 = 33605028

Showing the first eight; more decompositions exist.
