Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33506820, here are decompositions:

19 + 33506801 = 33506820
23 + 33506797 = 33506820
43 + 33506777 = 33506820
47 + 33506773 = 33506820
79 + 33506741 = 33506820
131 + 33506689 = 33506820
157 + 33506663 = 33506820
197 + 33506623 = 33506820

Showing the first eight; more decompositions exist.
