Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33609918, here are decompositions:

5 + 33609913 = 33609918
11 + 33609907 = 33609918
19 + 33609899 = 33609918
31 + 33609887 = 33609918
101 + 33609817 = 33609918
131 + 33609787 = 33609918
149 + 33609769 = 33609918
157 + 33609761 = 33609918

Showing the first eight; more decompositions exist.
