Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33471840, here are decompositions:

29 + 33471811 = 33471840
37 + 33471803 = 33471840
41 + 33471799 = 33471840
67 + 33471773 = 33471840
71 + 33471769 = 33471840
107 + 33471733 = 33471840
131 + 33471709 = 33471840
151 + 33471689 = 33471840

Showing the first eight; more decompositions exist.
