Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33493818, here are decompositions:

5 + 33493813 = 33493818
11 + 33493807 = 33493818
41 + 33493777 = 33493818
101 + 33493717 = 33493818
179 + 33493639 = 33493818
191 + 33493627 = 33493818
199 + 33493619 = 33493818
227 + 33493591 = 33493818

Showing the first eight; more decompositions exist.
