Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33605520, here are decompositions:

29 + 33605491 = 33605520
41 + 33605479 = 33605520
79 + 33605441 = 33605520
101 + 33605419 = 33605520
103 + 33605417 = 33605520
127 + 33605393 = 33605520
131 + 33605389 = 33605520
211 + 33605309 = 33605520

Showing the first eight; more decompositions exist.
