Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33605840, here are decompositions:

3 + 33605837 = 33605840
43 + 33605797 = 33605840
127 + 33605713 = 33605840
139 + 33605701 = 33605840
157 + 33605683 = 33605840
193 + 33605647 = 33605840
349 + 33605491 = 33605840
397 + 33605443 = 33605840

Showing the first eight; more decompositions exist.
