Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33499820, here are decompositions:

7 + 33499813 = 33499820
19 + 33499801 = 33499820
31 + 33499789 = 33499820
37 + 33499783 = 33499820
43 + 33499777 = 33499820
61 + 33499759 = 33499820
157 + 33499663 = 33499820
199 + 33499621 = 33499820

Showing the first eight; more decompositions exist.
