Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33561442, here are decompositions:

29 + 33561413 = 33561442
53 + 33561389 = 33561442
179 + 33561263 = 33561442
251 + 33561191 = 33561442
269 + 33561173 = 33561442
281 + 33561161 = 33561442
353 + 33561089 = 33561442
389 + 33561053 = 33561442

Showing the first eight; more decompositions exist.
