Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33481930, here are decompositions:

11 + 33481919 = 33481930
17 + 33481913 = 33481930
47 + 33481883 = 33481930
113 + 33481817 = 33481930
173 + 33481757 = 33481930
179 + 33481751 = 33481930
191 + 33481739 = 33481930
353 + 33481577 = 33481930

Showing the first eight; more decompositions exist.
