Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33581406, here are decompositions:

13 + 33581393 = 33581406
107 + 33581299 = 33581406
109 + 33581297 = 33581406
127 + 33581279 = 33581406
139 + 33581267 = 33581406
149 + 33581257 = 33581406
197 + 33581209 = 33581406
283 + 33581123 = 33581406

Showing the first eight; more decompositions exist.
