Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33512820, here are decompositions:

13 + 33512807 = 33512820
37 + 33512783 = 33512820
41 + 33512779 = 33512820
67 + 33512753 = 33512820
73 + 33512747 = 33512820
97 + 33512723 = 33512820
139 + 33512681 = 33512820
149 + 33512671 = 33512820

Showing the first eight; more decompositions exist.
