Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33601820, here are decompositions:

3 + 33601817 = 33601820
19 + 33601801 = 33601820
67 + 33601753 = 33601820
97 + 33601723 = 33601820
127 + 33601693 = 33601820
163 + 33601657 = 33601820
193 + 33601627 = 33601820
271 + 33601549 = 33601820

Showing the first eight; more decompositions exist.
