Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33507872, here are decompositions:

19 + 33507853 = 33507872
109 + 33507763 = 33507872
193 + 33507679 = 33507872
241 + 33507631 = 33507872
271 + 33507601 = 33507872
331 + 33507541 = 33507872
613 + 33507259 = 33507872
661 + 33507211 = 33507872

Showing the first eight; more decompositions exist.
