Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33507920, here are decompositions:

7 + 33507913 = 33507920
13 + 33507907 = 33507920
31 + 33507889 = 33507920
67 + 33507853 = 33507920
139 + 33507781 = 33507920
157 + 33507763 = 33507920
241 + 33507679 = 33507920
379 + 33507541 = 33507920

Showing the first eight; more decompositions exist.
