Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33625878, here are decompositions:

29 + 33625849 = 33625878
37 + 33625841 = 33625878
47 + 33625831 = 33625878
61 + 33625817 = 33625878
109 + 33625769 = 33625878
127 + 33625751 = 33625878
197 + 33625681 = 33625878
199 + 33625679 = 33625878

Showing the first eight; more decompositions exist.
