Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33473820, here are decompositions:

41 + 33473779 = 33473820
43 + 33473777 = 33473820
53 + 33473767 = 33473820
71 + 33473749 = 33473820
73 + 33473747 = 33473820
137 + 33473683 = 33473820
139 + 33473681 = 33473820
167 + 33473653 = 33473820

Showing the first eight; more decompositions exist.
