Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33518638, here are decompositions:

17 + 33518621 = 33518638
29 + 33518609 = 33518638
47 + 33518591 = 33518638
311 + 33518327 = 33518638
557 + 33518081 = 33518638
617 + 33518021 = 33518638
827 + 33517811 = 33518638
941 + 33517697 = 33518638

Showing the first eight; more decompositions exist.
