Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33481938, here are decompositions:

19 + 33481919 = 33481938
29 + 33481909 = 33481938
101 + 33481837 = 33481938
107 + 33481831 = 33481938
131 + 33481807 = 33481938
137 + 33481801 = 33481938
179 + 33481759 = 33481938
181 + 33481757 = 33481938

Showing the first eight; more decompositions exist.
