Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33561644, here are decompositions:

3 + 33561641 = 33561644
37 + 33561607 = 33561644
73 + 33561571 = 33561644
283 + 33561361 = 33561644
373 + 33561271 = 33561644
463 + 33561181 = 33561644
541 + 33561103 = 33561644
577 + 33561067 = 33561644

Showing the first eight; more decompositions exist.
