Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33609978, here are decompositions:

7 + 33609971 = 33609978
19 + 33609959 = 33609978
47 + 33609931 = 33609978
71 + 33609907 = 33609978
79 + 33609899 = 33609978
191 + 33609787 = 33609978
229 + 33609749 = 33609978
257 + 33609721 = 33609978

Showing the first eight; more decompositions exist.
