Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33545390, here are decompositions:

7 + 33545383 = 33545390
13 + 33545377 = 33545390
19 + 33545371 = 33545390
61 + 33545329 = 33545390
79 + 33545311 = 33545390
139 + 33545251 = 33545390
163 + 33545227 = 33545390
199 + 33545191 = 33545390

Showing the first eight; more decompositions exist.
