Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33481290, here are decompositions:

43 + 33481247 = 33481290
97 + 33481193 = 33481290
103 + 33481187 = 33481290
127 + 33481163 = 33481290
131 + 33481159 = 33481290
173 + 33481117 = 33481290
191 + 33481099 = 33481290
197 + 33481093 = 33481290

Showing the first eight; more decompositions exist.
