Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33561974, here are decompositions:

31 + 33561943 = 33561974
97 + 33561877 = 33561974
157 + 33561817 = 33561974
223 + 33561751 = 33561974
367 + 33561607 = 33561974
613 + 33561361 = 33561974
631 + 33561343 = 33561974
907 + 33561067 = 33561974

Showing the first eight; more decompositions exist.
