Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33471990, here are decompositions:

11 + 33471979 = 33471990
17 + 33471973 = 33471990
37 + 33471953 = 33471990
43 + 33471947 = 33471990
73 + 33471917 = 33471990
137 + 33471853 = 33471990
179 + 33471811 = 33471990
191 + 33471799 = 33471990

Showing the first eight; more decompositions exist.
