Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33605890, here are decompositions:

41 + 33605849 = 33605890
47 + 33605843 = 33605890
53 + 33605837 = 33605890
83 + 33605807 = 33605890
167 + 33605723 = 33605890
173 + 33605717 = 33605890
347 + 33605543 = 33605890
359 + 33605531 = 33605890

Showing the first eight; more decompositions exist.
