Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33561904, here are decompositions:

23 + 33561881 = 33561904
53 + 33561851 = 33561904
137 + 33561767 = 33561904
251 + 33561653 = 33561904
263 + 33561641 = 33561904
293 + 33561611 = 33561904
347 + 33561557 = 33561904
353 + 33561551 = 33561904

Showing the first eight; more decompositions exist.
