Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33561398, here are decompositions:

19 + 33561379 = 33561398
37 + 33561361 = 33561398
127 + 33561271 = 33561398
229 + 33561169 = 33561398
331 + 33561067 = 33561398
379 + 33561019 = 33561398
547 + 33560851 = 33561398
571 + 33560827 = 33561398

Showing the first eight; more decompositions exist.
