Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33561800, here are decompositions:

31 + 33561769 = 33561800
127 + 33561673 = 33561800
193 + 33561607 = 33561800
229 + 33561571 = 33561800
241 + 33561559 = 33561800
331 + 33561469 = 33561800
421 + 33561379 = 33561800
439 + 33561361 = 33561800

Showing the first eight; more decompositions exist.
