Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33507740, here are decompositions:

3 + 33507737 = 33507740
61 + 33507679 = 33507740
109 + 33507631 = 33507740
139 + 33507601 = 33507740
163 + 33507577 = 33507740
199 + 33507541 = 33507740
421 + 33507319 = 33507740
433 + 33507307 = 33507740

Showing the first eight; more decompositions exist.
