Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33581394, here are decompositions:

13 + 33581381 = 33581394
43 + 33581351 = 33581394
73 + 33581321 = 33581394
97 + 33581297 = 33581394
103 + 33581291 = 33581394
107 + 33581287 = 33581394
113 + 33581281 = 33581394
127 + 33581267 = 33581394

Showing the first eight; more decompositions exist.
