Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33605972, here are decompositions:

3 + 33605969 = 33605972
13 + 33605959 = 33605972
109 + 33605863 = 33605972
223 + 33605749 = 33605972
271 + 33605701 = 33605972
709 + 33605263 = 33605972
823 + 33605149 = 33605972
1039 + 33604933 = 33605972

Showing the first eight; more decompositions exist.
