Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33573920, here are decompositions:

7 + 33573913 = 33573920
13 + 33573907 = 33573920
31 + 33573889 = 33573920
43 + 33573877 = 33573920
97 + 33573823 = 33573920
109 + 33573811 = 33573920
139 + 33573781 = 33573920
241 + 33573679 = 33573920

Showing the first eight; more decompositions exist.
