Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33481980, here are decompositions:

23 + 33481957 = 33481980
61 + 33481919 = 33481980
67 + 33481913 = 33481980
71 + 33481909 = 33481980
97 + 33481883 = 33481980
127 + 33481853 = 33481980
149 + 33481831 = 33481980
163 + 33481817 = 33481980

Showing the first eight; more decompositions exist.
