Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33605072, here are decompositions:

31 + 33605041 = 33605072
79 + 33604993 = 33605072
103 + 33604969 = 33605072
139 + 33604933 = 33605072
199 + 33604873 = 33605072
463 + 33604609 = 33605072
499 + 33604573 = 33605072
643 + 33604429 = 33605072

Showing the first eight; more decompositions exist.
