Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33605908, here are decompositions:

59 + 33605849 = 33605908
71 + 33605837 = 33605908
101 + 33605807 = 33605908
179 + 33605729 = 33605908
191 + 33605717 = 33605908
239 + 33605669 = 33605908
317 + 33605591 = 33605908
467 + 33605441 = 33605908

Showing the first eight; more decompositions exist.
