Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33519900, here are decompositions:

23 + 33519877 = 33519900
61 + 33519839 = 33519900
107 + 33519793 = 33519900
109 + 33519791 = 33519900
131 + 33519769 = 33519900
149 + 33519751 = 33519900
151 + 33519749 = 33519900
173 + 33519727 = 33519900

Showing the first eight; more decompositions exist.
