Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33605642, here are decompositions:

151 + 33605491 = 33605642
163 + 33605479 = 33605642
199 + 33605443 = 33605642
223 + 33605419 = 33605642
349 + 33605293 = 33605642
373 + 33605269 = 33605642
379 + 33605263 = 33605642
601 + 33605041 = 33605642

Showing the first eight; more decompositions exist.
