Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33519942, here are decompositions:

13 + 33519929 = 33519942
19 + 33519923 = 33519942
103 + 33519839 = 33519942
149 + 33519793 = 33519942
151 + 33519791 = 33519942
173 + 33519769 = 33519942
191 + 33519751 = 33519942
193 + 33519749 = 33519942

Showing the first eight; more decompositions exist.
