Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33619920, here are decompositions:

73 + 33619847 = 33619920
109 + 33619811 = 33619920
149 + 33619771 = 33619920
157 + 33619763 = 33619920
163 + 33619757 = 33619920
167 + 33619753 = 33619920
181 + 33619739 = 33619920
233 + 33619687 = 33619920

Showing the first eight; more decompositions exist.
